USER GUIDE CONVENTIONS

Virtual DMIS is designed to run on a number of different computers and operating systems.

While many of these platforms are very similar, the look and feel from one system to the next varies enough that it is not possible to write a guide that matches exactly what the user will experience.

In an effort to present a consistent documentation that is easy to read with information that can be applied to a number of platforms the conventions described below are used.

There are four basic areas:

TYPOGRAPHICAL This is the look and feel of this guide.

KEYBOARD A description of key sequences.

VIRTUAL DMIS How this guide describes the Virtual DMIS Graphical User Interface.

MOUSE How some of the many types of mice interact with Virtual DMIS

TYPOGRAPHICAL CONVENTIONS

Menu Selection

Text seen in Virtual DMIS menu selections, or titles have been placed in bold characters for its first occurrence.

DMIS Syntax

DMIS syntax is typed using uppercase lettering. When examples of code are to be presented, the font will change to a Times New Roman 10 -point font.

THIS IS AN EXAMPLE OF TIMES NEW ROMAN 10 POINT UPPERCASE THAT IS USED FOR DMIS CODE.

KEYBOARD CONVENTIONS

Keyboards come in many shapes and sizes; each one has its own unique layout and labeling. In addition to confusing, labeling the function of a key can change from one application to the next. Users are urged to take a few minutes and review the notes below to learn the function of keys and key combinations in the Virtual DMIS environment.

1) The keys on your keyboard may not be labeled exactly as they are in the manual.

2) The keys on your keyboard may not be in the same location described in this manual.

3) Beware of the keys in the numerical keypad area. Keys on the numerical keypad are not the same as keys in the main keyboard area. On some keyboards the ENTER key in the numerical keypad area sends a different code to the computer than the ENTER key in the main keyboard area. This also applies to the dual functions keys like 8 and 4.

Well-informed and perceptive users never assume that keys on the numerical keypad will always function as advertised.

2

Introduction

Key-names

Keyboards have keys and each key has a name, a "key-name". There is a key on the right it is larger than the other keys. On many keyboards, the word "enter" is printed on top of this key. In this guide, key-names are shown in capital letters.

For example:

1) The Control key is shown as CTRL in this guide.

2) The Escape key is shown as ESC in this guide.

3) The Enter key is shown as ENTER in this guide

4) The Alternate key is shown as ALT in this guide

Single Keys

Each key on a keyboard has a function and this function varies from one application to the next. The specific functions of keys in the Virtual DMIS application are listed below.

ENTER

ENTER and RETURN, are two common names for this key. Regardless of the name, these keys perform the same action in Virtual DMIS. In the documentation, 'Press ENTER' means that either ENTER or RETURN may be pressed, unless specifically instructed otherwise.

TAB

The TAB key will move the cursor from field to field within a window.

Numeric Keypad Keys

On most computer systems, the keyboard is extended to include a numeric keypad on the right-hand side. These keys may be used for numeric input. The NUM LOCK key must be activated. Usually there is a light on the keyboard, indicating when NUM LOCK has been activated

ARROW KEYS (a4,0.=:>)

The arrow keys are used to manipulate the graphics on the screen. To see more information to the right of the machine, press the right arrow, etc. All four directions are available (left, right, up, down).

HOME, END, PAGE UP, PAGE DOWN

These keys may be used to move the cursor through the database area of your screen. These may be used once a program has been created

3

Virtual DMIS

Hot Keys

Keys can be used in combination as shortcut keys. This is commonly used in Virtual DMIS.

For example:

1. ALT+P means to hold down the ALT key and while still holding down the ALT key pressing the P key.

2. ALT+SHIFT+C means to hold down the ALT and SHIFT keys and while still holding down the ALT and SHIFT keys pressing the C key

Keys can be used in sequence as shortcut keys.

1. ALT P means to press and release each of these keys in order; press the ALT key and release (often a menu bar is then highlighted) then press the P key.

2. ALT F C means to press and release each of these keys in order; press the ALT key and release (often a menu bar is highlighted at this juncture), then press the F key and release, then press the C key.

Accelerator Keys

Functions on a menu in some applications have a key-name in that function underlined. These functions can be accessed with a single keystroke when the menu is active.

Virtual DMIS supports accelerator keys for all the pull down menus on the Systems Utilities Menus.

The key-name that points to the accelerator are always the keys are always the first letter or number in the name and are not underlined in Virtual DMIS.

NOTE:

When more than one item in the pull down begins with the same letter, pressing the accelerator key a second time will bring the user to the next selection with the same beginning letter.

For example, the hot key ALT P will open the project menu and then pressing the accelerator, will bring the user to the Import CAD selection; pressing the key, a second time will bring the user to Import Sensor Data. This holds true for all pull down menus.

Labels

When labels of features, sensors, tolerances, etc. are referred to in this document, the default system labels and names are assumed.

Menu Selections

When prompted to select from a Virtual DMIS menu, the text of the menu selection will be typed in bold lettering. If there is an associated icon, the icon may be included in the text as well.

LMB The left button (referred to as LMB in this manual) is the primary button. Most selections in the software are made using the LMB. Selections are made using a single 'click'.

Functions may also be performed by pressing and holding a mouse button. The movement of the mouse while a button is activated will determine the amount of change on the screen.

RMB The right mouse button (referred to as RMB in this manual) will present a variety of menus depending on where the pointer was resting when the right button was activated.

POINT Means to position the mouse pointer until the tip of the pointer rests on whatever you wish to point to on the screen.

CLICK Means to press and then immediately release the mouse button without moving the mouse.

DOUBLE CLICK Means to quickly click two times. This is used to activate an application.

For example, 'Double click' on the Virtual DMIS logo to enter the software. The speed of the double click may be set by right clicking on 'My computer' on your desktop. Select open. Open the control panel on the menu and select mouse. The slider bar on the button tab will allow you to increase or decrease the speed of the 'Double click'. There is a test area next to the slider where you may test your speed.

DRAG 'Drag' means to point and then hold down the mouse button as you move the mouse

DRAG AND DROP means to point; hold the mouse button down over an item; slide the mouse across the screen and release the mouse button when the item is over the desired location.

BOX 'Box' is created by holding the LMB and dragging the pointer on the screen diagonally. This function is used in the best-fit feature construction. This feature is also used to zoom in on an area of the Graphics area of the screen.

Installing Virtual DMIS

INSTALLING VIRTUAL DMIS

Note: Virtual DMIS is installed at the factory when a CMM is shipped. If a retrofit kit was purchased, the software will be installed on the new computer that was supplied with the kit. Installation of the software should not be required.

Virtual DMIS software is protected by a License key. There are two types on license keys; one requires a parallel port and the other uses a USB port. Each License key has it's own unique serial number and a license number associated with it. Each license number is generated by the Virtual DMIS central facility. As EACH SERIAL NUMBER IS MATCHED TO A SINGLE LICENSE KEY, it is vital that in situations where there are multiple copies of Virtual DMIS, each License key remains with the system for which it was intended.

After installation ensure you have the following files backed up on a disk:

C:\winhome l\vms.ini

This file contains the password required for installation of the software and all of the tunable parameters (size, feeds and speeds, etc.) for your machine.

C:\vmshome2thin\errormap.txt

This file contains the error correction data from the laser calibration. The file name generally matches the serial number of your CMM.

For complete documentation, refer to the Virtual DMIS installation guide. 3

After a few moments, (depending on the speed and memory capacity of the computer) expect to see the following screen:

There is no User intervention required at this point. This screen illustrates normal on-line startup.

NOTE: When running on-line, Virtual DMIS operates a program that controls the CMM in real time. This program is called the motion controller driver. This background process has a number of critical tasks running all the time. When Virtual DMIS is stopped, the driver requires a few moments to complete these tasks. Do not re-start Virtual DMIS until the motion controller driver icon has closed and has left the task bar.

After a brief moment, (depending on the speed and memory capacity of the computer) a splash screen will appear. There is no User intervention required. This screen illustrates normal startup; there is no visual difference between off and on-line startup at this point.

HOMING THE CMM

If this screen is displayed the CMM is ready to home.

Homing the system means to move to a preset location. This location is often referred to as the machine zero. Sending a machine to its home position allows the controller to read in the error map for the Dimensional Measuring Equipment. The error map is a mathematical adjustment correcting any structural geometry issues electronically. The error map is a fine tune adjustment of the system.

DCC MACHINES ONLY

• Press the servo button on the controller if you have a DCC machine.

MANUAL MACHINES ONLY

• For a Manual Machine position the machine physically in the proper Home location before LMB on the home icon

HOMING THE CMM FOR ALL MACHINES

• Select the HOME icon and single click with the LMB.

The HOME icon is the little house on the right at the top of the screen.

OR

• Select Tools from the system menu along the top of the screen;

• Select Machine Status from the pull down menu;

• Select Machine from the pop-up window;

• Select Go Home Icon from the menu on the screen. For more information on this procedure, go to Page 57 of this guide.

Once a CMM has been sent to the home position, the Graphics view of the CMM should coincide with the physical machine. If the Virtual DMIS software has been installed as a retrofit the graphics may not be an exact match.

If the hardware for the controller is in the computer used on the CMM, sending the CMM to home is only required when the computer has been shut down and restarted.

For systems with external controllers, the system is sent home when the controller has been powered off or if the controller has been reloaded.

Once Virtual DMIS is opened, the homing icon will automatically appear. It is not necessary to home the CMM if the emergency stop button has been engaged.

CAD files are accessible from local directories, CD ROMs, or across network drives. When selecting the import CAD option a file management window appear.

NOTE: Any file that is imported into the Virtual DMIS UI must reside on the local computer. Translated files may not be imported from the network or from CD.

Although the file formats IGES, STEP, VRML, IV, DXF and VDA are supported, they must be translated first using one of the available Virtual DMIS translators.

In the file management window the default type is RLE. RLE files contain precision data of the imported geometry. An RLE file will not be displayed without the associated WRL file. WRL files by themselves can be displayed however the WRL by itself may not be as precise as the .RLE file.

Virtual DMIS CAD Translation

Virtual DMIS supports several neutral file formats; IGES, STEP, and VDA. These files are translated into two files, a WRL (VRML) file used for display and an RLE file used to store mathematical data. VRML and IV files do not require translation.

If an IGES file is translated, the file name remains the same and an extension is added to the end of the file name once the translation is complete.

Example - SAMPLE.IGS will be converted to SAMPLE.IGS.WRL and. SAMPLE.IGS.RLE.

While a file is translating, it is possible to continue working within Virtual DMIS. The translator may be run in the background.

The CAD Translator Shortcut is automatically placed on the desktop when Virtual DMIS is installed. If the short cuts are not on the desktop. The *.exe files required are found in the C:\vmshome\Vmlges directory. T CAD

Precision Mode Affects the face transformation. Modifying the precision may increase the probability of successful translation. Level 1 is lowest and Default, and level 3 is highest precision.

Wire Mode This mode affects both face and wire translation. There are 5 modes for IGES and 2 for STEP files. This can reorder the wire frame to correct missing surfaces or gaps between patches.

30


Visual Tolerance

Entity Filtering

This setting only affects the .WRL file by changing the number of triangles for each face. The larger the Visual tolerance setting, the fewer triangles involved in the graphical view, resulting in a smaller WRL file. If the translated file is too large or difficult to manipulate in Virtual DMIS, the visual tolerance value may be increased and the file translated a second time. A lower visual tolerance may fill gaps in surface data that appear at a higher Visual Tolerance value.

Select the entities to include or exclude by checking the appropriate boxes.

Mirror Plane Sets the plane to mirror about if a mirrored part is desired

Virtual DMIS requires the CAD files are stored on the local computer for translation. Translation of files stored on a network drive may be slow and the translated files may be corrupted.

A log file will record the options selected for the translation. The log file name is the combined with CAD file name. For example, the log file for IMS Block Surface.igs will be "IMS Block Surfaceigs.translator_options.log". The file will be created in the folder containing the CAD file.

IMPORT SENSOR DATA

Imports previously defined sensors from existing projects. If sensors were calibrated in the existing project, they will be available under the actual sensor list. If the sensors were not calibrated, they will appear only under the nominal sensor list.

It is important to note that sensors brought into a project in this manner do not get included in the definition of the sensors in the DMIS program. The code will be written to change to the various sensors and as long as the sensors are in the sensor database, the program will run. However, If the DMIS program is to be transported to a different CMM, or the programmer plans on using the Virtual DMIS Simplified User Interface (SUI 4), it is important that the code to import the sensor database is written to the part program. 5

Caution: If any sensor data is defined prior to importing sensor data, it will be overwritten without warning.

IMPORT COORDINATE SYSTEM

Imports previously defined coordinate systems from existing projects. If any labels are duplicated, the existing coordinate system will be renamed. Files are renamed as follows: coordinate system being imported has the label PCS1 and that label is present, the existing label is renamed to PCS1_2.

Coordinate systems may be recalled into a DMIS program in the same manner as sensors.

IMPORT TOLERANCE DATA

This will import previously defined tolerance data.

When a program is created and tolerancing is defined, the tolerance data is stored in the 'Vol' directory associated with that project name. If the parts to be programmed use general tolerances, it is possible to set up one tolerance file with these general tolerances defined.

The program would call up this tolerance file using the 'IMPORT TOLERANCE DATA' command.

Once tolerance data has been imported, the User will not be required to type in any tolerance information. To apply a tolerance drag and drop tolerance information from the tolerance database into any open tolerance window.

When importing tolerance data containing DIAM and CORTOL data, the current settings will be overwritten and the imported values will become the default. If the imported tolerance data does not contain these two tolerance types, the current default values remain active. Here is an example of recalling data from a stored project

Recalled sensor data, named coordinate systems or tolerance labels are stored by project name. Because the data is stored by project name, the recall screens appear identical, however only the requested data will be input.

IMPORT FEATURES

This will import previously saved project features.

An example of application would be to set up a fixture in one project and measure a part in a second. If the user required a tolerance between a fixture feature and a part feature, it would be necessary to import the feature data from the fixture project.

IMPORT DMIS

This allows the importation of programs created previously in either Virtual DMIS off-line or Virtual DMIS on-line. The previously defined DMIS programs are then resident in the program database area for use. The program may be modified, or executed from the database area.

This option also may be used to import programs created using other vendor software. The vendor of the proprietary software must supply the DMIS posting processor: This enables users to create programs on alternate systems and run the program utilizing Virtual DMIS.

IMPORT OTHER LANGUAGES

Available in Off-Line only, this function allows the import of other OEM programming languages.

The languages available are:

1) ACCUDAT

2) AVAIL

3) TUTOR

4) MASTER

5) CMEAS

Virtual DMIS will translate the above languages into the standard DMIS syntax, allowing projects writhen using various OEM CMM programming languages to be run on a Virtual DMIS system.

EXPORT CAD

The purpose of this key is to take the geometry data created during an inspection and translate the data to IGES format. This allows the CMM to become a part of the design process by accommodating reverse engineering.

Virtual DMIS exports all features as B-Spline lines and points.

RECENT PROJECT FILES

The "Recent Project Files" keeps a list of the last 4 Projects the user has been working on.

The 1 st entry in this list is a Backup project that Virtual DMIS automatically creates. This allows for instant Data recovery should the system shut down due to any unforeseen reason (crash). At Virtual DMIS start up, after a previous session crash, will generate a Question window to ask whether one wants to reload the temporary project saved from the previous session.

The 2nd through the 4th entry are projects previously worked on. By selecting the desired entry, Virtual DMIS will load all data that belongs to that project, allowing for very quick switching between different projects

EXIT VIRTUAL DMIS

The exit command will close the Virtual DMIS window and prompt the User to save the current project. Once the window is closed, any data that was not saved is lost. Click on the line 'Exit Virtual DMIS', and a file management screen will appear. If you would like to save the current project, type in a name on the line titled File name. All files saved in this area will have the extension `.prj' added automatically.

Virtual DMIS will prompt users to save the current project ONLY if the current project has changed since the last save.

DEV, covers tolerances and deviations

VEC, controls the number of decimal places output for vectors

You may change the default value for any group by using the down arrow to select the desired group and then the down arrow to the right of the numeric window. This will bring up a list of numbers below the default value from one to ten. Click on the value of your choice to change the setting. The drop town list provides up to 10 decimal places for significant digits. Please remember the accuracy on your CMM. 2 significant digits when using millimeters and 3 when working in Imperial units are typical. Some programmers may increase these by 1 (3 in millimeters and 4 in inches). Remember the capability of y our CMM when setting these parameters.

Video last frame pause - Allows the user to determine how long the help video will remain on the screen once it has completed running. A setting of '1000' will keep the picture for one second, where a setting of 10,000 will keep the picture for ten seconds. This setting is stored in the VMS.INI 6 file.

Whisker Magnification - Graphics display will display form error whiskers for a measured feature when it is dragged and dropped on the graphic area. Form errors will not be displayed for constructed or nominal features. The size of the whisker is a reflection of the error and the whisker magnification. This value is read at start up from the VMS.ini file and is stored to the file when Virtual DMIS is exited properly. The sizes of the whiskers are a combination of the view arrangement and the actual form error on the feature. While displaying form error graphically, the user may zoom in on the feature so that it is the only item on the screen. If that is the case, the whiskers may have a smaller value in the setup as opposed to the size required for the complete view of the part. Remember while displaying form graphically that the error on a feature will change from one part to the next. The whisker magnification may need constant adjustment.

SPH-BN D

This dialogue box is used to prevent hitting the shank of the probe during calibration. These parameters are of particular interest when calibrating styli with very small ruby tips or if the angle of inclination is greater than ninety degrees. The sphere-bounding vector is also used to define the orientation of the mounting stem for the calibration artifact. Stem may be referred to as Stalk by some users If the stem of the calibration artifact is not orthogonal to the CMM surface this vector must be updated to provide the capability of automatic sphere measurement.

Note:

These settings will affect the probe path available if Automatic Sphere measure is to be used during a part program

For systems using the Renishaw TM UCC controllers, the sphere-bounding vector is defined in the VMS.ini file under the [RENISHAW] section of the file. The vector stored in the VMS.INI file is required by the UCC controller for use of the analogue scanning heads. The sensor calibration routine for the scanning heads is a function of the controller, NOT Virtual DMIS.

Sphere bounding vector This defines how the MGAGE (calibration artifact) has been mounted on the CMM table.

If a standard artifact is being used, the vector will be 0.00, 0.00, -1.00. Specifically the vector defines a plane that intersects the calibration sphere at the equator with the vector of the plane aimed into the mounting stem.

Sphere bounding ratio This value is used to avoid collisions with the stem of the qualification artifact.

The value defines what percentage of the sphere is available above the bounding plane to the automatic calibration routine (in this case above means in the direction of the plane vector). In order to clear the mounting stem while calibrating a star tip or a sensor with an angle of inclination greater than ninety degrees, the system is installed using a sphere bounding ratio of 67%. A larger the mounting stem requires a larger value entered into the window. In the diagram on the following page, the Bounding ratio removes approximately 33% of the sphere surface that is available to the probe. The image above indicates a sphere-bounding ratio of 63% (100%-37%). If the stem were larger, the value entered into the window would be smaller.

Sphere bounding dist. This value is used to prevent hitting the shank of the probe when calibrating styli with small diameter tips. A secondary plane is defined X-distance below the bounding plane (in this case below means in the opposite direction of the plane vector) The area between the bounding plane and the offset plane is no longer available to the sensor for calibration. The vector of this plane is orthogonal to the active sensor and is updated with each sensor selection. Hence, once the plane is defined the sensor may be safely calibrated in any position.

LEARN

Comment out all sensor definition during create This option prevents errors in the sensor calibration status. As a program is created, in learn mode, the definition line for the sensors is commented out to prevent overwriting calibrated sensors during the re-running of a part program.

Sensor definition lines are required if the DMIS code is to be run without loading the full project. If this is the case, the user must calibrate the sensor immediately after definition for a calibrated sensor to be used in a program.

However if the user is running a Virtual DMIS PROJECT the sensor database is automatically loaded into the project, and the user may choose to calibrate or not depending on the status of the probes. When running a program with sensor definitions commented out, Virtual DMIS automatically looks for the appropriate sensor in the sensor database. If the sensor database was not loaded, (in the case of Import DMIS) the sensors would not be present and the definition would be required.

Move coordinate will allow the User to switch the joystick between part coordinate system and machine coordinate system.

Once the part coordinate system option has been enabled, it will continuously update with every Part Coordinate system transformation.

This selection is reset to Machine when Virtual DMIS is exited. It is not reset to machine when a New Project is opened. It may appear that it is reset when a New Project is opened if the coordinate system is reset to MCS. At this point, the joystick motion will move along the machine coordinate system because it is the current part coordinate system.

Programmable back off is the global back-off distance for all points measured in joystick mode. When activated, this allows the user to force a back-off distance for all points taken in joy-sticking mode. If this is not activated, the Retract distance may be changed in the probe settings menu.

NOTE:

1. This function is machine controller dependant.

2. When running in DCC mode the back off distance applied will be determined by the current RETRCT value.

Direction allows the user to change the direction of the joystick controls. One application would be when using the joystick box at the back of the CMM table. The user may change the direction of the joysticks. This makes those awkward measurements at the back of the machine a bit easier.

An outside diameter will not require large retract distances on the probe settings to avoid a collision. If this item is not enabled, you must increase the probe approach and retract settings before running any automatic calibration routines. If this is not done, there will be collisions during the routine. Continuous motion may be switched on and off within a part program.

Enable Smart Measure

This activates the Smart Measure algorithms. When enabled, the user is not required to select the feature type about to be measured. The Smart measure algorithm will determine the feature types as they are being measured. This tool is a time saver when programming on-line on a large machine, the amount of keyboard interaction being greatly reduced.

To measure with Smart Measure simply go and measure the feature. The open measure window will display the counters in RED rather than in Yellow. The counter will go up in numbers as hits are added to the feature, not counting down as in the normal measurement mode. When one point is taken, the window will read and label a Point. As hits are added, the window will update the feature type accordingly.

If two hits are taken in directions that cannot possibly solve a line, a buzzer will sound indicating those 2 points do not solve a feature. This occurs when measuring a circle. The feature measure window will display 2 points in the buffer until the 3 ro hit is taken. At this point, the feature measure window will change to Circle.

To complete measurement of one feature and move to the next press the enter key on the teach pendant or click on the calculate feature now, a green check on the measurement window.

If, while measuring the feature displayed is not the anticipated feature type the user can switch the feature by selecting the proper feature from the Feature tool bar.

For example:

• 8 points have been collected and the measure window is displaying a cone

• The desired feature type is Cylinder

• LMB on the Cylinder Icon before selecting the Green Check

Individual points may be deleted by pressing, cancel on the keypad or delete on the measurement window.

Min Feat. Points

This screen allows the User to change the minimum number of points required in order to calculate a feature. The values in this area are stored in the VMS.INI file. The values listed in the green (shaded) columns are unchangeable and display the mathematical minima required to calculate the feature.

Once the minimum number of points has been increased, the feature will no longer allow the user to finish the feature at the mathematical minimum. The present number of points must be collected.

The minimum feature points for SLOT feature has been hard coded into Virtual DMIS.

When measuring a Round ended slot, the number of points to be collected is 6.

When measuring a Square Slot, the number of points to be collected is 8. When measuring a square slot, each line on the slot requires 2 hits.

Do not take more than the minimum points for slot.

For detailed descriptions of feature measurement techniques, refer to the features section of this document. Starting at Page 141

There is no return to default settings. The values can be re-entered at any time.

Enable Warning

This option is turned on and off, as the user requires. When using a CAD file to program, this option will draw a cube around the solid model on the screen. The cube is transparent so the model may still be viewed, yet still allowing the User to visualize the minimum clearances required. The User must enable the warning upon entering Virtual DMIS or when required. While programming, with the warning box enabled, a collision path will activate a Collision Manipulation window. At this time, the user may manually manipulate the sensor around the collision. If the Check box in the System status is selected, Virtual DMIS will automatically resolve the collision. (Refer to Configuration, System Settings System Status in the Online help, or in this document).

To activate the sounds and voice of Virtual DMIS, the user must select this feature only one time. When the Voice help is enabled, the user may click the RMB over any area or item on the users interface and a help file describing this button will play.

Sounds will be played while moving over the feature menu, taking points and completing features. The User may follow the status of the program by listening to the sounds provided. This is very useful on larger machines or manual machines where the User is not always right at the computer screen viewing the system status.

Enable Video Help

The status of this option is stored in the VMS.INI file. If the user does not want this item selected at start up, the Video help must be `off prior to exiting the software.

Once the Video help is enabled, the user may click the RMB to play videos of the following menus; features, constructions, sensors, tolerances and alignments. If the voice help is activated, voice files linked to the videos and menu selections will play with the videos.

Set Help Languages

There are eleven different languages available to the user. This will change the language of the tool tips for the icons of Virtual DMIS.

Changing to an unsupported language will cause the system to place exclamation marks after all the tool tips of Virtual DMIS and any error messages that appear will only have the INFO number and an exclamation mark to identify them.

It is not necessary to exit Virtual DMIS when Help Languages are switched. However, the language is stored at the time of exit, and Virtual DMIS will open with the User Interface set to the last selected language.

CONSTRUCTIONS

AO-L'

1 1 A5 zz 4* a grio

This menu bar allows users to create new features from existing features through geometric applications. Examples of various constructions are found on page 157 of this document.

Features used for construction may be actual or nominal features.

Actual features are features that have been defined and then measured or constructed.

Nominal features are features that have been defined and not yet measured.

Some constructions can create different elements. For Example: "Tangential to 2 circles". When more than one resultant feature is possible, all possibilities can be viewed by selecting the down arrow in the Calculated Feature Window.

To view the solutions in the graphics area LMB on the drop down list and select each feature in the Calculated Feature, window. The feature displayed in that window will appear as a green temporary feature in the graphics area. When the next feature is selected and the current is not applied, the temporary feature will disappear.

The characteristics of the calculated feature are listed on the right side of the construction window. Direction of a linear feature may be reversed by selecting the REVERSE VECTOR key (green key) to the right of the calculated feature field.

After one of the available solutions is selected, the constructed feature is removed from the list of possible solutions and the construction window remains open. This prevents duplication of constructed features.

Once all possible results have been constructed, the construction window will automatically close. This does not mean that if there is more than one solution every option must be calculated.

Once the required feature has been constructed, select the APPLY button in the lower right-hand corner of the window. To exit the construction window, select the 'X' in the upper right corner of the construction window or make a new menu selection.

If the fields in the construction window contain features that do not solve the selected construction, the Calculated feature type window and the feature label field will remain empty. If a calculation is requested that is not arithmetically sound, the APPLY icon is unavailable to the user.

When a feature construction window has two features available for input, the feature identified as `featl' is the last measured feature and leat2' is the second last feature measured. These features are automatically placed into these fields. Constructed features do not automatically update into these fields. If features other than the last two are required for the construction, features from the database may be dragged into the input fields, typed in or using Object select the User may click on the required features.

This tool bar may be customized using the smart editor.

TOLERANCES

// J4l 1Y 4 ► © 11k, e"'N

In all of the tolerance windows, an icon toggles between a feature control frame and calculator is displayed at the bottom of the window. By default, Virtual DMIS opens all tolerance windows with the option to calculate a tolerance on specified features. By clicking on the 'calculate tolerance' icon, the function of the window is changed to tolerance definition.

z•-• 03M

2E1

Tolerance definitions may be used to predefine a list of general tolerances to be used in the program. While calculating tolerances will define a tolerance and calculate a tolerance when the APPLY button is selected.

While inputting tolerance values, it is not necessary to input the leading zeros. Example: Tolerance + 0.10, may be input as .1 or 0.1

While placing the tolerance values in the input fields, it is necessary to place a minus `-' sign in front of the negative tolerance value if the tolerance has a negative value. The sign is not assumed by Virtual DMIS.

Using Predefined Tolerances

Once a tolerance has been defined, the user may drag and drop the definition from the tolerance database into the Label field of any tolerance window. This will cause the tolerance window to display the appropriate selection from the tolerance menu. By using this method, the User is not required to re-enter similar tolerance data while programming.

As with the constructions, if a calculation is requested that is not mathematically sound, the APPLY button is unavailable. All tolerances are calculated using the ANSI Y-14.5M standard for Geometrical Dimensioning and Tolerancing.

For more information on Tolerance application, please refer to page 173 of this document.

Note:

In the VMS.INI file is as setting that will link a size tolerance to a feature.

TOFEATLINK=1

If this setting is switched on, every tolerance will have a unique label. It will not be possible to apply DIA1 to more than one circle. This is true even if the size tolerance for several diameters is constant.

2) Perform Sensor Length and mount from the tool bar displayed above. This will have the user measure the qualification artifact two times. Once the routine is completed, Virtual DMIS will have an accurate mathematical model of the sensor assembly. The Sensor Length and mount routine is also useful if the stylus is customized for a specific jog (shaft bent). When this routine is executed, the new length and direction of the probe head is stored in the VMS.INI file. If using Standard Renishaw parts for the probe configuration, and the position of the probe head has been certified with the sensor length and mount during an earlier session of Virtual DMIS, the routine is NOT necessary.

If the sensor auto calibration routine fails by missing the calibration artifact, it may be due to incorrect values in the senor length and mount. If this is the case, run the application.

Once Virtual DMIS has the correct data for the sensor length, programming may be performed without the need of first generating a sensor list and calibrating a sensor list. Virtual DMIS will have a reasonably accurate location for any sensor position allowing the user to program and generate the required list of sensors prior to calibration. Once a program has been completed, the sensor list may be easily a quickly calibrated.

Calibration may be performed one sensor position at a time using tools on the Sensor Tool Bar, or by suing the pop up menu in the Nominal Sensor Database.

The sensor functions are linked to several areas of the user interface. For a more detailed description, please refer to Using Virtual DMIS in this guide or in the Virtual DMIS On Line help, For the Beginner.

COORDINATE SYSTEMS

Once a part has been placed on the CMM table a Part Coordinate System (PCS) must be created from datum features.

The tools for creating the datum reference frame are available on this tool bar.

This tool bar allows the user to create and manage the coordinate systems. Virtual DMIS has additional tools for complex coordinate systems in the software keys on this tool bar.

Virtual DMIS provides the tools required to generate Right Hand Coordinate Systems.

Right Hand Rule

It states that the direction of one axis combined with the direction of a second axis determines the direction of the third axis. The three axes are mutually perpendicular to one another.

When working with a 3D coordinate system in Virtual DMIS, the major axis is identified as the first axis in the work plane and the minor axis is the second listed axis calculated 90 degrees CCW to the major axis. The projection axis is not listed.

Work plane XY

Work plane YZ

Work plane ZX

When building a coordinate system, each feature used as a datum of the coordinate system will set everything it can without undoing any of the previous steps.

To understand what is happening with the coordinate system, hold out your 'Right' hand. With the palm of your hand facing up, curl in the small finger and the one next to it. The three remaining fingers represent the relationship of the axes in the coordinate system. Stand at the front of the CMM, look down the Y+ axis, you may notice your thumb is pointing along the machine X+ axis. Your index finger is pointing along the machine Y+ axis, and your middle finger is pointing along the machine Z+ axis. There are several methods to performing this relationship. You may find an easier method for determining the axial relationships.


For further information on the Coordinate System Tool Bar, refer to the Using Virtual DMIS Section, paqe 181.

User Interface

PROGRAM

The Program tool bar supplies the tools to direct the execution and development of part programs.

This tool bar supplies the tools for running part programs, opening and saving DMIS programs, stopping the system at specific intervals and opens a DMIS editor.


The last icon on the tool bar has several functions:

1. While running a program, hitting the "Stop Light" will cause the controller to stop immediately.

2. If there is output sitting in the print buffer, hitting the "Stop Light" will force the printer to send any data in the buffer directly to the printer.

3. If variable have been declared, hitting the "Stop Light" will reset the variables database. There will be no declared variables after this button is selected. To reactivate the variables, the user must step through the declaration portion of the part program.

NOTE: Alt+C will perform the same task as the "Stop Immediately" button.

MY TOOL BAR

My Tool Bar allows the user to place previously defined macros into the software. This is also useful if the user is running only a few parts. Customizing this tool bar allows the user to create a uniquely personal system.

This tool bar also enables the user to read previously defined macros and DMIS files into an existing project. Macro files are given the extension ".mco" and DMIS files are given the extension ".dms". The files are not evaluated while they are read into the project; hence, the extensions are simply a useful user identifier.

In a single user environment, the files are stored in "VMSHOME\Users\Macro and VMSHOME\Users\Program". For a multi-user environment, the path is "VMSHOME\UsersVogname\Macro and VMSHOME\UsersVogname\Program".

This tool bar must be customized using the smart editor, and is empty at installation.

HELP

This button activates the on-line help function of Virtual DMIS.

On-line help is an electronic User Guide. Users are encouraged to investigate this tool.

Help appears on top of the Virtual DMIS Graphics area; to return to inspection simply select the Minimize button and help will drop to the Windows Tool Bar. To recall help hold down the ALT key and tap the TAB key, when "Virtual DMIS 2006 Help" appears in the selection box release the ALT key and Help will appear over the Graphics area again.

SMART TOOL BAR

The smart tool bar is one of the most unique and powerful features of Virtual DMIS. The tool bar itself is displayed below the Main Tool bar and changes dynamically with each different selection from the main bar. Not only does the smart tool bar update itself with each selection from the main tool bar, it also changes dynamically with each geometric feature measured.

The Smart Tool Bar has two functions.

1. The primary function of the Smart Tool Bar is to view the functions typically applicable to the last two measured features. This area has been described as a metrology calculator. The user may set specific tasks linked to combinations of features. To customize Virtual DMIS, use the Smart Editor selection under Tools. This has been described under the Tools drop down menu selection located on the System Utilities Menu.

The options that are presented with each selection from the main tool bar are standard choices and set as default in Virtual DMIS. These default selections however can easily be changed and modified, by either the user or a system administrator. This allows the software to be customized for each installation requirements if desired. To modify the Smart Tool bar, select the Smart Editor under Menu>Tools>Smart Editor option.

NOTE:

The last two measured features may also be used to lock the projection feature of subsequently measured features. Please refer to "LAST TWO FEATURES" in the "DATABASE AREA".

2. The secondary function of the Smart Tool Bar is to display all of the menu options associated with items on the Main Tool Bar. The first image below shows the contents of the smart tool bar, with the system having just measured a circle and a plane, as indicated by the two left hand icons. To the right of the two features is a selection of the most commonly used options that could be required of a circle and/or a plane.

FEATURES

Features are geometric elements, often simple, for example a single point or a plane, sometimes complex, like a surface or a gear. All supported features are iconized on the Feature Measurement Tool Bar.

ACTUAL FEATURES

Actual features are the results of measurement or constructions. Virtual DMIS supports the construction of nominal features; for a constructed feature to be calculated as an actual feature the first feature used in construction or both features must be actual features.

For an actual feature to exist a nominal feature must first be defined. This is normally done automatically by Virtual DMIS.

A special case exists when building a program using Virtual DMIS and a CMM. When building a program without CAD nominal and LEARN: ON, the Actual features and initial nominal features will be derived from the measured features.

NOMINAL FEATURES

Nominal features — Define the "as-designed" value, they may be keyed in features or features generated using a CAD model. The Nominal is the value with which the Actual value is compared for computing tolerance conditions.

A special case exists when building a program using Virtual DMIS and a CMM. When building a program without CAD nominal data and LEARN: ON, the Actual features and initial nominal features will be derived from the measured features. How the nominal features are derived may be parameterized using System Utilities Menu > Configuration > System Settings > Quick Meas > Nominal (size or location) Rounding Digits.

Nominal feature values may be edited after they are initially generated.

Open the Edit feature window in the Feature Database with a RMB click on the feature to be edited. This activates a pop up menu. From this menu, select Edit Nominal. From here, the nominal data may be modified. Once the APPLY button is selected, the changes are recorded to the database.

Grids generated on an incorrect datum parts will result in incorrectly projected points. Confirm your part coordinate system before using this function or any other measurement.

How to generate a grid of points on a CAD model:

1) Import CAD Model

2) Datum Part and move part to current part coordinate system.

3) In the Database area RMB on the "Point" Icon Select generate grid points. The default grid covers the entire CAD model.

The size and location of the grid can be adjusted by changing the values in the start and end windows. The point density can be changed by changing the step (increment) values in the "IncX" and "IncY" boxes. The grid plane can be reoriented by changing the values in the Direction box.

4) When the desired plane is illustrated simply select the green check with the LMB and the points will be projected to the surface of the CAD model.

Variables are data-types that MUST be declared. The Variables database is used for High Level Language Programmers. It provides database utilities to the programmer. Variables may be declared for use in calculations such as volume or area, or creation of Headers, where the operator must input serial numbers or Shift or Lot information.

As with all other titles in the database area, a double click on the primary title will collapse or expand the list.

Intgr The data type integer is a signed whole number such as 1 or —1. It is a value to be used in calculations. For example, loops in programs will use whole numbers only.

Real is any number requiring precision greater than an integer, it may be a whole number. For example, a circle diameter may result in a whole number.

Char Allows for the substitution of alphanumeric data to be passed as text. An example - charvar=text Character variables may be alphanumeric 1, 2, 3, 4 A, B, C, D,

RMB on one of the Intgr, Real or Char categories brings up the pop-up menu. These titles are gray when no variables are defined.

Name Labels may be applied at the time of creation, or the programmer may choose to use the nomenclature provided by Virtual DMIS. Once the Variable has been defined, the label cannot be altered. Variable name checking against DMIS major and minor words is only performed when DMIS is at 4.0 or higher level.

Value sets the numerical value for the Variable

Obtain, when available, allows the user to drag either Actual or Nominal features into the input field.

Index provides a list of available parameters to assign to the Declared Variable.

DMIS DECL is a drop down list with two options. It is only available when Learn ON. This controls where the Variable Declaration appears in the part program.

Last Decl will send the definition of the current variable to the line in the part program where the last declaration was defined.

Current Line will place the defined variable where the pointer is currently at in the DMIS program.

93

User Interface

In the DMIS code, the directory structure in the variables database will grow accordingly, sorting variables according to type. The variables database will display the variable data as it is generated in the part program.

Once a variable has been declared, it may not be declared a second time. This becomes evident when debugging a part program or re-running a program without reaching the

;41 ENDFIL command. The variables database is cleared when the STOP IMMEDIATELY icon is selected on the Program tool bar. If an error message

appears while executing a program, providing the option to select Cancel or OK to continue, the variables database is not cleared.

The DMIS language provides a range of Declaration techniques. If using the DMIS standard while programming, the following variable declarations are available.

DECL/LOCAL DECL/COMMON DECL/GLOBAL

DECL/LOCAL will provide a variable that is declared within a macro. Once the ENDMAC line is executed, the variables are removed from the database.

DECL/COMMON generates a variable that is constant throughout the current session of Virtual DMIS. These variables are not removed at the endfil line nor when the Stop immediately icon is selected. Common variables do not invoke an error message if the declaration statement is executed while the variable resides in the database. This variable type is only removed from the database area by exiting Virtual DMIS.

DECL/GLOBAL is the variable type used by Virtual DMIS. If Global does not appear in the declaration line, Virtual DMIS assumes GLOBAL. Global variables are available to the part program and are cleared on ENDFIL or the stop immediately icon.

To cancel a search in progress, press ESC.

DMIS Dependencies — Any given inspection program may use several different sensor positions and several local datum schemes. When executing a previously written program or program segment the active sensor or coordinate system may no longer match the coordinate system or sensor used in the earlier portion of the program. When enabled, DMIS Dependencies can automatically resolve these issues.

To enable, select the pop-up menu by using the RMB in the program data base area. Position the mouse over DMIS dependencies and select the field with the LMB. Expect the window to close.

When reopened, the window will show a check mark next to the DMIS Dependencies field.

The example illustrates the warnings and resolution provided when DMIS Dependencies are enabled.

With this powerful tool, there is no longer a need to temporarily modify code when testing a program in real time.

In this example, the Current Sensor does not match the DMIS sensor. As there is a conflict the DMIS Dependencies menu automatically pops up. This allows the User to make an informed decision before continuing.

If the check box next to the filed labeled "Activate DMIS Sensor" is selected with the LMB and "Continue Run" is selected the active coordinate system will be changed to match the program and the program will execute from the selected line.

The User may also exit by selecting "Stop Execution"

Last 2 measured features

The Last 2 Measured Features performs three functions. They are: 1. Controlling which functions appear on the Smart tool bar 2. Locking vectors to a feature. 3. Auto Project

Controlling the Smart tool bar

As features are measured, the Smart tool bar is automatically updated. It presents the most common functions applicable to the last 2 MEASURED features. Users may also drag and drop features from the database area into the last 2 measured features fields. This causes the Smart tool bar to update with respect to the selected features.

Locking Vectors to a feature

Double click on a feature residing in the last 2 measured feature icon area will Lock the l ei feature. The icon will display the image on the left. Once a feature is locked, the vector I

of the locked feature becomes the vector of any subsequently measured 2D features. Although all feature types can have the lock applied to them individually, the application is only a valid Metrology application for the following feature types: Plane Cylinder Cone 3d Constructed line

It is recommended that as soon as the user has finished using the Locked feature that the feature has the lock removed

Auto Project

RMB on a Locked feature reveals a pop up menu (displayed in image below)

Auto Project Onto Locked Feature(PL1) vo Auto Project Onto Locked Feature

A right mouse click on the feature will re-display the menu so the user may confirm the sate (on or off). Move the mouse off the menu and LMB to exit.

ELJ Once enabled the Icon changes indicating any features measured will be measured with the vector of the locked feature and a second feature will be created at the locked feature. For example, if a circle was measured 1 mm below a locked plane, CR1 would be generated with the measure and then CR1_P would automatically be calculated at the plane. This second feature will be a true 3D feature; meaning that the feature will be repeatable along all three axes, regardless of manual or automatic point collection

It is recommended that as soon as the user has finished using the Locked feature that the feature has the lock removed

If both features in this area are locked, the last measured feature takes precedence. If the features were dragged onto the fields and both were locked, the left field takes precedence.

Selecting any feature Icon from the Feature Measurement Tool Bar will display the Feature Measurement Window shown in the graphics area, above.

There are twelve informational and control areas in the Feature Measurement Window, beginning with the Feature Label and ending with Relative Measurement.

Feature Label

If previously defined feature is not used the label increments sequentially based on the nomenclature existing in Virtual DMIS, for example CR1 then CR2 for circle or CIRCLE1 then CIRCLE2 if the nomenclature has been redefined by the user in Change Feature Id, located under Tools in the System Utilities Menu.

The user may also re-type any desired syntactically valid label desired. For example DATUM A_ in place of PL1.

A previously defined label may be dragged from the Database Area and the feature measured, manually or if properly defined in automatic mode, on DCC CMM's.

103

User Interface

Point Counter In normal measurement based on the number of desired points, this counter will decrement until all the points are taken. Please refer to additional notes under Finish Measurement later in this section.

Smart Measure mode the point counter will increment and the numbers in the counter will be displayed in Red.

Finish Measurement Allows the user to end a feature measurement regardless of the number of points required in the point buffer. Once the minimum number of points has been reached, the finish measurement icon becomes active.

Auto Measure Is active when the feature being measured has been previously defined and the label is dragged from the 'database area into the label area of the Feature Measurement Window. Circles, points, lines, spheres and Cylinders may be measured in auto mode.

Point Counter Slider Bar The number of points to be collected during the feature measurement is increased or decreased using the slider bar. The altered number will remain in the measurement window for all subsequent features of the same type, until the number of points is changed again.

The maximum number of points to be measured on a geometrical item is nine hundred ninety-nine. Curves and Surface scans do not have this limit. Performance dramatically degrades above five hundred points on all except the most powerful computers.

Once the minimum number of hits has been recorded, the feature will be calculated and the form will begin calculation as well. If the output window is open during measurement, the output will update with each point taken beyond the minimum set requirement.

Scan Is supported for lines circles, cylinders, arcs, curves and surfaces. A previously defined circle may be scanned after taking two points while a surface requires five points to define the direction and boundary. 13

Delete Selected Point This feature allows the user to look at the form error introduced by each point within an uncompleted feature, select obvious errors and delete the points. Once the feature has been completed, this item is not available. The selected point appears in red in the histogram. Unless a point is selected by the user, the last point is highlighted for, review and delete options

Point Buffer Increments as points are taken. The user may select any point in the buffer with the LMB, and delete it using Delete Selected Point.

Deviation Informational only, shows maximum deviation and error (deviation) of last measured point.

Histogram Gives an overall view of the form of the feature being measured. Clicking on a bar within the histogram selects the actual point within the feature. This allows the user to view the form introduced by the selected point.

13 For more information on feature scan and surface scan, refer to the scanning document on the Virtual DMIS CD.

104

Feature Tool Bar

Obtain Control Window The active CAD model (Geom) label may be dragged from the database area into this window; planes, cylinders and spheres are also supported. When a model or geometry is in this window, the vectors for the measured feature are obtained from the model or geometry. Measured features are nominally defined at the surface of the selected entity.

Projection This is an animated icon provided to indicate the application of the Obtain Control Window.

Relative Measure is supported for feature point, circle, arc and slot. Selecting the down arrow on a supported feature will display the following window.

There are three supported formats:

Vector Build

Vector build obtains a vector from a locally measured plane and uses this vector to measure the defined feature. Two variables are required. "Ni" is the number of points to be measured in the local plane. "Dist" defines how far away from the edge of the nominal feature the local plane will be measured. All points in the local plane are evenly distributed around the nominal feature.

Drag the label of a nominal or actual feature from the database and the vector of the feature will be used in the measurement of the defined feature.

Fixed Axis

When selected the vector is locked to a single axis relative to the active part coordinate system.

PROGRAM STATUS TOOL BAR

DO PROG IPRCCM: ON iVii(PLAN: XY xiaNKTN: MM IANaE; ANGDEC OORD: CART !LEARN; ON

MODE

There re 3 modes of programming available with this first key.

Manual

Manual mode creates a part program requiring operator interface. Features within the progran, will be measured by the User either with the joystick or by manipulating the probe by hand. The measurement technique is dependant on the type of CMM.

This mode of programming is used on manual machines where there are no servos to drive the machine and semi-automatic machines where the joystick supplies the only power of movement. The method of programming may also require the use of manual mode. For instance, the program may require manual set up of the coordinate system or of a temporary coordinate system.

Auto

Auto mode is the easiest form of programming. This method uses the probe settings,-clearance planes automatic collision avoidance" (if activated) to determine clearance moves and probe position. Auto mode also makes use of the systems ability for circular interpolation 15 .

Caution: All lines of programming between the feature MEAS and ENDMEAS command are ignore by the program (i.e. PTMEAS, GOTO and sensor change commands). If there are specifi moves or contact points that are required within the measurement of a feature, Auto Mode i not the program mode to use. While running a feature in Auto mode, Virtual DMIS can ch ck for the first GOTO move in the measurement block and check for inconsistent use of the s nsor. This function is activated using the following menu selections:

• Configuration

• System Settings

• Automode

• Check first GOTO inside MEAS block

• Check for inconsistent use of Sensor and

While measuring a feature using Auto mode, the sensor approach and retract values are checked against machine travel. If the sensors approach and retract values exceed machine travel, a warning message is displayed.

14 Go to System Tool Bar, Configuration, System Settings and the Sys Status Tab for more information on Collision Avoidance.

15 Go to section of machines settings for more information on Circular interpolation.

107

User Interface

Prog

Program mode is easiest described as copycat mode. When running a program that was created in program mode, the probe will move exactly where programmed. The GOTO points are read and executed within features (between the feature MEAS and ENDMEAS commands in the DMIS code).

PROBE COMP

Probe compensation has two settings, On and Off. This toggle switch displays the current setting. There are very few occasions to turn the probe compensation Off. One example would be for scanning. While measuring points on an unknown surface the User may choose to turn probe compensation off. When these points are read into a CAD station, they may be adjusted by probe radius to negate the possibility of probe compensation errors. Probe compensation status does not effect the calibration.

WKPLANE

Work plane determines the aOtive plane for the measurement and evaluation of two-dimensional features. The work plane may be changed at any time during a program as required by the inspection. While setting up the initial coordinate system, the work plane may not be changed until the orientation (direction of the axes) has been determined.

XY

Two-dimensional features will be viewed along the Z-axis.

YZ

Two-dimensional features will be viewed along the X-axis.

ZX

Two-dimensional features will be viewed along the Y-axis.

LENGTH

This selection determines the unit of measurement currently in use in the program.

MM Millimeter CM Centimeter IN Inch FT Feet M Meter

The unit of measurement may be switched at any time during the programming sequence. In F some facilities, it may be ne ssary to report the results of an inspection in both inches and millimeters. This dual reporti g may be programmed into the part program. The change of units will be reflected in thevalues after changing the units. It is not necessary to re-measure a feature to report in more than one unit.

108

Program Status Tool Bar

ANGLE

There are two systems available for measuring angles. This selection, similar to the length selection, determines the unit of angular measurement for the program. As with length, the unit of angular measurement may be switched at any time during the programming sequence. If while programming angles between features are to be reported as Degree : Minutes: Seconds There i a switch In the angle between tolerance window. If the switch is not turned on, refer to the MS.ini section of the online help file.

ANGDEC

Sets the angular unit to decimal units. Each one-degree is divided into one hundred units.

ANG RAD

Sets the angular units to Radians. In many theoretical applications, the angle is measured as part of a circle.

Radians are defined as The length of the arc subtending the angle An angle so defined is expressed in circular measure, having the radian as a unit. The circumference of a circle is pi times its diameter, 2 pi radians equal 360 degrees.

User Interface

COORDINATE

The coordinate setting sets t e type of coordinate to be reported by the Digital Read Out (DRO). This also determines he setting for output purposes. Two types of coordinate reporting are available.

CART — This sets the display to the Cartesian coordinate system. The Cartesian coordinate system consists of three axes perpendicular to each other. Virtual DMIS uses the right hand rule in coordinate system definition. The axes are referred to as X, Y and Z. The work planes are defined using two of the t ree axes, for example the XY work plane. These axes are oriented with the positive Y-a is running 90 degrees counter clockwise to the positive X-axis. The Z-axis is 90 degrees cou ter clockwise to the X-axis and the Y-axis.

POL — This sets the display t Polar coordinates. Virtual DMIS analyzes two-dimensional polar coordinates. The axes isplayed are R (radial distance), A (angular location) and H (height). Radial distance is a alculation of distance along the longitudinal axis and the transverse axis of the feature Polar location is simply a different means with which to report the location of a feature.

For example, if a feature was located at X30.00 mm Y50.00 mm

the polar location could be c lculated using the Pythagorean theorem and trigonometry

R = square root (Deviation of X squared + Deviation of Y squared) = 58.31 Where deviation is distance from the origin.

While the Angular location may be calculated using trigonometry

A = ARC TAN (delta y/delta x) = 59.03 degrees

Rather than calculate these values out when required, simply change the coordinate readings from Cartesian to polar. This tool is helpful when working with bolt hole patterns.

It is important to note that th features are stored in the feature database as either Polar or Cartesian entities. If the locat on of a Cartesian entity requires Polar output, the programmer must perform the Tolerance f nction of Coordinate located on the tolerance tool bar. Nominal values may be edited in the • utput window as either Polar or Cartesian coordinates, but once save in the output window is elected, the feature is stored with the coordinate type. Any output from the output windo will reflect the coordinate setting that was present when the Save button was selected.

LEARN

Learn toggles between on an• off.

Learn ON — When learn mod is on, a project is created. The project will store DMIS program, sensors, coordinate systems, features (nominal and actual), raw data output files and tolerance data.

Learn OFF — This allows the .ystem to be utilized as an inspection station. Virtual DMIS allows the system to measur and evaluate features but the methods used for these functions are not stored. Ste •s taken while learn mode is turned off are not repeatable without a User

HINT: if while running a proven program, one feature will not measure automatically because the part is out of spec; ensure learn mode is OFF, change to manual mode, run the line of code to measure the offendin feature, return PROG setting to either AUTO or PROG (as the program originally set) and ntinue running from current line.

Show Feature Graphical Processor The feature Graphical Processor (FGP) application designed to allow users to analyze measured data by removing unreasonable point data from a feature. Unreasonable flyers may be caused by dirt on the feature, or a bad hit with a probe, vibration in the lab. Whatever the cause, the FGP is available to the user to remove flyers.

Once the FGP is opened, the feature in question may be dragged from the database into the new window.

The FGP allows the user to:

1) Edit the current feature

^.VirtualDMIS Feature Graphical Processor

Generate a new feature with flyers removed

Graphically display nominal and actual feature

aim

4) Show points within the feature and the properties of each point

5) Magnification of form error to show points

6) Display form of feature as a form distribution chart

7) Zoom in on the isolated feature

The F P supports the following features:

• Line • Plane • Circle

• Cylinder • Arc • Curve

When the FGP is opened, a feature from the database are may be dragged into the open window. This will cause the feature measure window to open. Points may be selected in the open window and then those points sent to Virtual DMIS for measure. The probe will not move tO measure the points. The FGP will cause Virtual DMIS to automatically generate a new feliture using only the selected points.

Surface Point This is actual "click and measure", points and vectors are automatically derived from the CAD model.

To work with these functions, a CAD model must be active in the graphics area, and the measurement and the pick and measure surface point window must be open. With these windows open, points may be selected on the CAD model. After the desired number of points are sel cted, the User may measure the part in real time or if learn is on, add the measu ennent code to a developing program.

Selecting this icon will add the measurement code to a developing program. 1)41 This button sends the nominal data from the CAD file to the DMIS program. In order to measure the features generated when DMIS was selected, the user

must go to the Iconized DMIS database and run the appropriate coed.

Selecting this icon will measure the part in real time and if learn is on, add the measurement code to a developing program. When this is selected, the nominal data equals the actual for the part program.

Surface Point with Vector Build

When measuring material that can vary from the nominal, for example sheet metal, it may be desirable to obtain an actual vector before measuring a point on the surface. This measurement routine obtains the actual vector of a point from a locally measured plane.

Select a point on the surface and choose the real time or add to program Icon; expect the menu illustrated below to appear.

There are two parameters to modify; first, the number of points to be used to define the relative vector plane and second the diameter of

the point pattern. When the desired entries are made, select Apply.

This illustration shows the three points taken to build the vector plane and the measured point in the center.

Select the surface to be measured and two points will be appear, one on the surface and one on the edge. Both the surface point (flush) and the edge point (gap) can be output.

Choose the real time or add to program Icon; expect the menu illustrated on the following page to appear.

There are three parameters available to modify. The vector plane option can be turned on or off; the number of points to be used to define the relative vector plane and the diameter of the point pattern. When the entries are made, the diameter of the plane must be less than the distance from the edge set in the previous menu. When a valid environment is established, select Apply.

With the Edge point offset uscl to insert DMIS code into the DMIS item window, there is a pop up after the completion. The pop up asks whether the last point is needed. This is used with gasket scan definition. 19

NOTE:

It is not necessary to use vector build for the surface point. Faster measurement can be achieved by simply taking a single point on the surface. No matter which method is selected, the elevation of the edged po nt will be relative to the actual surface point.

The illustration shows the co pleted measurement. Note the parameters from the newly m asured point are retained for subsequent measurement.

Intersecting Edge Point

This measurement routine is designed to measure two intersecting edges.

The function is similar to Edge point however; in this case, the offset of both points can be individually controlled.

Hem Edge Point

This measurement routine is a variation of the Trim Edge point function. When hem Edge computes the elevation of the edge point, the number of folds is automatically added to the calculation.

Used in conjunction with Edge Point these functions are designed to measure sheet metal edges. These measurements are sometimes referred to as flush and gap.

two, three and four FOLDS are supported.

As this command is functionally identical to Edge Point, refer to the Edge Point section for a description of the subsequent screens.

Incremental — Will move a di tance from the current probe position. The destination if th probe head is shown in green, no moves are made until the "CHECK" mark is selected. M difying the values in the "Delta fields" allows the user to preview moves. Absolute — Will move to the coordinate specified relative to the current part-coordinate system. When absolute is selected, the current position is displayed.

Graphics Tool Bar

Picked Vector Move — Is used in conjunction with the pick-and-measure feature. The sensor will move along the vector of the last pick-and-measure point on the CAD model to the distance specified in the D window.

There are three variations:

VEC - Zero is the present location of the sensor, when the "CHECK" is selected the sensor moves the distance in D along a vector that is orthogonal (parallel in all three axis) to the selected feature. CLRMOVE - Zero is a point along the vector of the picked feature at the elevation of the feature, when the "CHECK" is selected the sensor moves the distance in D along a vector that is orthogonal (parallel in all three axis) to the selected feature. POSVEC -. Zero is at the selected point, when the "CHECK" is selected the sensor moves the distance in D along a vector that is orthogonal (parallel in all three axis) to the selected feature.

Sensor Vector Move This GOTO command will move the sensor along the vector of the active sensor. A positive move "retracts" the sensor. Feature Vector Move Drag a feature label from the database and the command works just like the Picked Vector Move, Manual Manipulation Move with LMB click and hold, the sensor may be moved around the screen. A green arrow is available through the sensor. Dragging the arrow moves the on-line CMM and places a GoTo Move in the part program once the green check in the GoTo window is applied. Offline -Tapping the CTRL key, switches axes. A cube is also activated around the sensor. Dragging this around allows the GoTo, to be programmed in the applicable work plane.

Vec CIrMove PosVec

NOTE: GOTO commands are relative to probe center. It is prudent to be aware of this common CMM convention when programming in areas with limited clearance.

Active Model

Virtual DMIS allows the importing of several CAD rnodels, however only one CAD model may be active at a time. To switch from one CAD model to the next select the Active Model icon and click on the desired model. Active models are displayed as solids in the graphics area, inactive models are translucent.

Active model may also be selected by selecting the model name in the database area with the RMB.

Move/Rotate Model

This is used after selecting 'Sit Model On Table' from the RMB menu in the graphics area.

These tools allow an offline user to (virtually) position a part on the CMM and begin programming.

Notice the coordinate system is not aligned to the part.

Selecting this icon draws a box around the CAD model. Select any corner LMB brings up a "hand icon", hold the mouse button down and the part can be rotated. Select the center of any of the planes surrounding the part and the part can be moved.

When the part is in the desired position on the CMM table, the part coordinate system must be set before measurement can begin.

When this function is applied to a model, a new coordinate system is stored in the Database section. When programming be careful to ensure the part is datumed by the program, and does not use the graphics manipulation of the model for the initial set up.

USING VIRTUAL DMIS FEATURE MEASUREMENT

There are twelve standard features supported by virtual DMIS and an optional gear measurement module.

The standard feature

• Feature Point

• Feature Line

• Feature Plane

• Feature ircle

• Feature ylinder

• Feature Cone

• Feature Sphere

• Feature Arc

• Feature llipse

• Feature lot

• Feature eneral Curve

• Feature Surface

• Feature Gear

Gear features are de cribed in a separate document available to customers who have purchased the optional module.

On the following pages, descriptions of how to measure the various features have been listed. Please note that when CAD data is referred to, the user must first have CAD data translated, imported and set to an appropriate coordinate system

When measuring feathres many variables help in making the decisions on how we will actually perform the measurements. Some of these variables are:

• Manual CMM vs. DCC

• CAD data or no CAD data

• Recognition of CAD elements

• Finite Point Measurement vs. Scan measure

• Probe type

• CMM Control ler

The methods listed below are an introduction to feature measurement. They describe various means by which the user may generate data. However to find out which methods are available to you, or to learn all the methods, it is recommended that the user attend a Virtual DMIS training course supplied by a licensed Virtual DMIS training facility.

POINT

When measuring a point with no CAD data, the direction of retraction is the vector of probe compensation used for calculating the point of contact. On an automatic CMM, the direction of retraction is opposite the direction of approach. On a manual machine, this may not be the

case. Users must be careful with point measurement. When using Point and Click measurement with CAD data, the nominal information from the CAD model will create the point vectors.

When using points in alignments, it is necessary to have control of the point. A measured point will have at best, one axis of control, along the direction of movement. A point measured manually, on an edge has no repeatability on the depth of the measurement. A point constructed at the intersection of two lines has two axes controlled. A point created from the intersection of two lines and projected onto a plane has complete control along all three axes. A point feature may be; a measured point, a constructed point, a center of a circle, an apex of a cone, a center of a sphere or a center of an ellipse or center of a slot. Each on of these examples has various levels of control associated with them.

When measured a point appears in the graphics area as a small cube. The size of the cube is inversely related to the percentage set in the Configuration, System Settings - System Tab, Zoom Graphics at man mode. If this value is set to none, the point will appear small yet visible in the volume of the table. For manual CMM operators it may be necessary to increase the size of the graphical point for targeting purposes.

Manual Measure:

To measure a point using the ' or Manually, simply open the point measure window and touch the probe to the part. When measuring a Point feature it is important to ensure that the approach vector is normal to the surface of the Ott

DCC Control

To measure a point with the CI automatically, there are several options:

1. Drag and drop a point from the feature database into the open measure window and select the auto measure icon in the measure window.

2. Using CAD data select Pick and Measure from the Graphics Tool bar

a. With the moulse LMB on a point on the CAD picture. This will place a point in the Pick and measure counter

b. Open the point measure window

c. LMB on theTeen check in the Pick and measure window and Virtual DMIS will drive the probe and m asure the selected point. In this case the Measured point Nominal will be created from the Actual point so Nominal = Actual.

4. Using CAD data to Generate nominal

a. Open the point Measure window

b. Drag and drop the GMODEL in the database into the input field at the bottom of the point measure window.

c. With the joystick, measure a point. Virtual DMIS will access the CAD file, and compare the point measured to the nearest CAD point on the model.

It is possible to set the number of points to be measured to a number greater than one. In these instances, only the last hit will be recorded as the resultant point.

In addition to traditional measurement, vector build is supported with feature point.

All feature measurement windows function in the same way. A detailed description of this window's functionality is covered in the Feature Measurement Tool Bar section of this manual.

Using Virtual DMIS

LINE

When measuring a line, the probe compensation is calculated perpendicular to the direction of the line, in the general direction of probe retraction. It is not necessary to retract normal to the line, the

calculation will result from the measured feature not from the direction of retract. If the output window is visible while measuring a line with more than the minimum required hits, you will see this window update with every hit beyond the minimum. While reviewing the output window, there are two sets of vectors, I J K and 11 J1 K1. The first set represents the direction the line was measured from the first hit to the last hit. The second set represents the vector perpendicular to the resultant line. This tells the program which side of the line to approach the material. When more than two hits are used in the measurement of a line, the direction of the line is calculated from the first to the second point.

A minimum of two points is required to measure a line. Lines are two-dimensional features requiring a plane to view them. A plane must be measured and either locked or rotated to, prior to measuring a line or the current work plane will be used to calculate the result of the measured line.

The illustration shows six points in the buffer. Deviation is displayed as each point is taken and individual points may be selected and deleted, this is a real time way to address false triggers.

Manual Measure:

To measure a line using the joystick or Manually, simply open the Line measure window and touch the probe to the part in two places (minimum). When measuring a Line feature it is important to ensure that the points collected are taken at the extreme ends of the line to be evaluated.

SPHERE

During measurement of a sphere, the probe compensation is calculated from the measured feature. If the sphere has been

previously defined, and exists in the Nominal Feature Database, the nominal feature is used to calculate probe compensation regardless of the approach directions. n INNER or OUTER parameter in the sphere definition will also det rmine the calculation of the measured feature, regardless of the act al sensor approach vectors.

Four points are required to calculate a sphere. Three hits on the equator of the sphere and on the extreme height of the sphere. A maximum of nine hundred ninety-nine hits may be recorded to calculate a sphere. If more than four hits are to be measured, the first four must calculate a sphere. If four hits are taken about the diameter of the sphere, an error message will play informing the User that the feature cannot be calculated. This is not true if the minimum number of points to be taken has been increased.

The illustration show six points in the buffer. Deviation is displayed only after sufficient points have been taken to define the fe ture, then individual points may be selected and deleted, this is a real time way to address false triggers.

Manual Measure

A minimum of three hits may be recorded to calculate a curve. Once the minimum number of hits has been recorded, the feature will be calculated and the form will be calculated as well. To measure a curve automatically; 21

1. Set the work plane on the system that applies to the curve.

Feature Measurement

CURVE

2. Set the points to be measured greater than three.

3. Measure the start point of the curve

4. Measure the direction of the curve and the end of the curve.

5. Manually ret rn the sensor to a position that is clear to the first point of the scan.

6. To run the s n, simply click on the auto-measure icon that has turned active in the measure window. Up to a maximum of 9,999 points may be collected during the curve scan.

i., The density of the hit is determined by the speed of the machine. The speed is proportionate to the density of the hits. T e curve is stored as a B-Spline entity.

Note: for customers using the RenishawTM controllers, the scan point density is controlled by the operator, not velocity.

If there is a hole in the material where the curve is to be measured, the user may have the probe skip the missing material using the following steps.

1. Follow steps 1 though 3 listed above

2. Measure the point where the scan is to interrupt

3. Measure the start point of the continuation

4. Touch a direction point

5. Touch the end of the scan segment.

7. Manually rek rn the sensor to a position that is clear to the first point of the scan.

8. To run the scan, simply click on the auto-measure icon that has turned active in the measure window.

This process of 3 defning points may be repeated as many times as necessary. When defining the scan path, ensure the Counter in the Curve Measure Window has more points than are being used to define the scan.

A curve is defined by three or more points. Once the minimum numbers of points have been exceeded, the Measure Window will display the deviation of the feature. Individual points within the feature may be selected and the deviation reviewed, and deleted if required.

ARC

During measurement of an arc, the probe compensation is calculated from the measured feature. If the arc has been previously defined, and exists in the Nominlal Feature Database, the nominal feature is used to calculate probe compensation regardless of the approach directions.

An INNER or OUTER parameter in the arc definition will also determine the calculation of the measured feature, regardless of the actual sensor approach vectors.

Three points are required to calculate an arc. Arcs are two-dimensional features requiring a plane to view them. A plane must be measured and either locked or rotated to, prior to measuring an arc. An arc can be evaluated for radius, angle between, circularity and distance between.

Feature Measurement

ELLIPSE

During measurement of an ellipse, the probe compensation is calculated from the measured feature. If the ellipse has been previously defined, and exists in the Nominal Feature Database, the

nominal feature is usr to calculate probe compensation regardless of the approach directions. n INNER or OUTER parameter in the ellipse definition will also determine the calculation of the measured feature, regardless of the actual sensor approach vectors.

Five points are required to calculate an ellipse. An ellipse is a two-dimensional feature requiring a plane to view it. A plane must be measured and either locked or rotated to, prior to easuring an ellipse.

An ellipse is defined y six or more points; the illustration shows seven of ten points in the buffer. Deviation is displayed only afte sufficient points have been taken to define the feature, then individual points may be selected and deleted this is a real time way to address false triggers.

To measure an ellipse, take three points at one end of the ellipse and three at the opposite end.

Relative measureme t is not supported by feature ellipse.

All feature measure ent windows function in the same way. A detailed description of this window's functionality is cover d in the Feature Measurement Tool Bar section of this manual.

SLOT

Slots are defined s either round or square. This will affect the measurement tec nique to be used on the feature. Please refer to the images below.

If the slot has been previous! defined, and exists in the Nominal Feature Database, the nominal featur is used to calculate probe compensation regardless of the approach d rections. An INNER or OUTER parameter in the slot definition will also deter ine the calculation of the measured feature, regardless of the actual sens r approach vectors. If the slot is not residing in the nominal feature database before it is measured, probe compensation is calculated using the final feature.

Slots are two-dimensional features requiring a plane to view them. Slots measured in the current work plane are measured relative to that plane .A plane can be measured and either locked or rotated to, prior to measuring a slot.

The relative measurement feature may be used to establish a local plane. A slot is defined by six and only six points, the illustration, shows three of six points in the buffer.

Feature Measurement

SURFACE

To measure a surface, the user must identify the area to be scanned.

Increase the number of hits to a value greater than four, (the actual number dos not effect the scan). The user will identify a patch by

manually taking points around the boundary of the proposed scan. Once the boundary has been identified, the auto measure icon is active. Move the sensor to a position clear to he first point of the scan. Selecting auto measure will activate a window us d to set up the direction of the scan and the number of rows to take in the scan. Once this has been set up, selecting OK will cause the system to measure the patch automatically

The density of the hits is determined by the speed of the machine. The speed is proportionate to the density of the hits. The surface is stored as a B-Spline entity.

A surface is defined y five or more points; the illustration above shows six points in the buffer. as with all features the individu I points may be selected and deleted, this is a real time way to address false triggers.

Relative measureme t is not supported by feature surface. 22

FEATURE CONSTRUCTION

This section describes the use of the construction windows. Each window is similar with two input fields, resultant feature, feature label, reverse vector and the resultant parameters. There are tables describing the results with the various construction options. Feature 1 represents input filed one, Feature 2 input field 2 and the resultant feature have been listed.

While working with the feature construction application, it is important to note that if one of the construction features is a Nominal feature, ALL resultant features for that particular construction will be Nominal Features.

Prior to selecting the PPLY button, the user may review the proposed resultant feature using the column on the right side of th applet, and the proposed feature is also displayed on the Graphics area of the UI. The resultant feature will be drawn using Green until The APPLY button is selected. Once the construction is applied, the Result nt feature is removed from the drop down list box and the feature is drawn in the appropriate Nominal r Actual Feature color.

When there is more t an one solution to a construction, the Drop down list box, listed above as the resultant feature, will provide all possible solutions to the construction.

I Projection — This co struction creates a shadow image of the selected feature coinciding with the focal feature. One of t e more common applications involves the projection of a circle onto a plane. The measured feature is moved along the vector of the plane until the distance between the two is zero. The pierce point of the planes' vector through the center of the circle becomes the location of the projected circle. The resulting feature (point or circle) is a stable, three-dimensional feature.

In this window, there is a ch k box available to project to the current work plane. If this is selected, Input Filed 2 is unavailable.

Note: All two-dimensional features are stored at the depth of measurement. In order to tolerance the location on all three axes, it le required that the feature be projected to the appropriate plane.

This statement is not true if Auto projection is active while measuring. The Auto projection will generate a projected feature onto the locked plane. The resultant feature will have the suffix "_P"

For more information on this function, refer to the Database section of this document, page 106, or the online help.

Line Plane Point The pierce point of the line through the plane is only available if the two features are not on the same plane.

Line Circle Point The intersection of al line and circle assumes the two features exist in the same plane. If the Line does not truly intersect the circle and is slightly off the tangent point, the intersection point will be calculated by projecting the centre point of the circle to the line. The maximum distance for this calculation is 0.10 mm. The resultant point will be located between the projected point and the circle edge.

Tangent — This calculation will create a tangent feature between 2 features. It is very important to place features in the proper order. When working with a line feature and a

point feature, the line must be in the Tan To input field, and the point feature must be in th Feature input field. If the tangent feature is available at any size, the target size may be input in the Size input field. If the size of the resultant feature has only one option, this value will be calculated reg rdless of the entry in the Size input field. The size entered represe its the radius of the desired result. The size must be keyed in prior to a ding the features to the input fields for this to take effect.

Holding the CTRL + LMB dur ng selection of features, will allow selection of features to be dropped into the input field.

Offset Plane —This construction will create a plane through three points that are not on the resultant plane. Ea h feature used to calculate the offset plane must be a point type feature. Points on a surface and spheres are typically used for offset planes. The points must have similar

vectors for this calculation to be accurate. The distance is keyed into the field beside the feature field. The numerical value represents the distance from the point feature to the plane. If the result is on the positive side of the points then the distances will all be positive distances.

An example of an offset plane construction has been included with the Offset Plane alignment. To verify the constructed feature, simply view the distance between each point and the offset plane. If the distance is not equal to the keyed-in distance, something went wrong during the input of the data.

Mirror — This calculation constructs a mirror image of a feature through a second feature. The second feature acts as the mirror.

Cast — Casting a feature allows the User to analyze separate components of a feature. The feature type being cast determines the available resultant features. Points, lines and planes are features created by the cast option.

This section describe the general use of each tolerance selection. Labels are automatically generated or may be changed to u er-defined labels by keying in the label. The applet for tolerance selections is a common dialog. Onc a nominal tolerance is defined, it may be dragged into any open tolerance window for evaluation. Next t the apply button, there is an active key. This key has two functions.

Evaluate Tolerance: The user is in this mode when sending data to the printer or to a file. Once the tolerances have been defined, the evaluate tolerance mode is activated. Features may be

dragged and dropped into the feature-input fields for analysis.

Define Tolerance: The user is in this mode when creating tolerances to be used throughout the program. General drawing tolerances may be inserted here. Once the tolerances have been

defined, the nominal tolerance label may be dragged and dropped into any tolerance window from the nominal tolerance database. The window will then reset to the selected tolerance type which enables programming to be more efficient. When using the Define Tolerance mode, the feature-input fields are not active.

Size – Size tolerance reads the size of the feature from the nominal definition. This tolerance will analyze features with bound7ies. For example; circles, spheres, cylinders and cones. The three values available to the user are diamete , radius and angle. To switch from one type to another simply click on the icon required. These item have been listed below.

In the tolerance wind w, the nominal input field is unavailable for input. There are two methods available to edit nominal size and location data.

Distance — Distance betwee two features may be analyzed in several ways. In order for a distance tolerance to be evaluated be een two lines, the lines must be parallel within two degrees. Using the Along and Type and the Limit dista ce fields supply many options for the User.

If measuring the distance be een 2 cylinders, the angle between the two cylinders MUST be less than 2 degrees. Distance is calculated using the position of feature 1, as seen by the axis of cylinder in the input field for feature 2.

If the angle between the two ylinders is larger than 2 degrees, the distance is the shortest distance between the two axes.

Along supplies the following .ptions:

Pt2Pt looks at the straight-lin distance between the two features.

X-axis evaluates the distan = between two features along the X-axis of the current coordinate system.

Y-axis evaluates the distance between two features along the Y-axis of the current coordinate system.

Z-axis evaluates the distance between two features along the Z-axis of the current coordinate system.

XY Plane evaluates the straight-line distance between the 2 features along the XY Work Plane.

YZ Plane evaluates the straight-line distance between the 2 features along the YZ Work Plane.

ZX Plane evaluates the straight-line distance between the 2 features along the ZX Work Plane.

Type is calculated along the .elected axis and has the following options:

None is the option if the feat res being evaluated have no size. For example: The distance between two points.

Maximum is the option used i the features being evaluated have size, and the line between the two features have more than one pierce point on one or both of the features.

For example: To calculate the overall length of a slot, the maximum distance between two circles would be recorded.

Average is the option selectee if the two features have size with only the center distance is required.

For example: To calculate the center-to-center distance of a slot. The option 'none' is interchangeable with this function.

Minimum is used to determine the wall thickness between two features of size.

Limit Distance is used in conj nction with the Along and Type options. When the distance is defined using an upper and lower specifica ion, select Limit distance. The upper and lower tolerance is switched to upper and lower limits and the nomi al field is now unavailable to the user.

Note: If the distance between two lines is to be calculated, and the lines are not parallel, the distance is taken perpendicular to featur one, through the midpoint of feature two.

Angle Between — This calculates the angle between two actual features. If the required angle is in a quadrant other than the angl found in quadrant one, key in the desired angle. The system will calculate the angle found in the proper quadrant. The exception to this rule is an input of 90 degrees. This will evaluate the angle between t e directions of the two lines.

To apply this tolerance drag and drop the required features into the input fields, type in the nominal angle, apply the required tolerance and select APPLY.

Parallelism — This calculates the parallelism of two actual features. The relative distance is calculated using the measured length of the reference feature. It is very important to place the reference feature in the reference-input field. Parallelism is calculated along the reference feature length. The nominal for this value is zero and therefore is not required for entry.

The tolerance band is unilateral; a negative tolerance is not displayed nor keyed in. Features must be within five degrees of one another for evaluation of this tolerance.

Perpendicularity —This calculates the perpendicularity of two actual features. The relative distance is calculated using the measured length of the reference feature. It is very important to place the reference feature in the reference-input field. The perpendicularity is calculated along the reference feature length. The nominal for this value is Zero and therefore is not required for entry. The tolerance band is unilateral; a negative tolerance is neither displayed nor keyed in.

Features must be within five degrees of one another for evaluation of this tolerance.

Angularity — This calculates he angularity between two actual features. For this calculation, a reference angle is required. The relative distance is calculated using the measured length of the reference feature. It is very important to place the reference feature in the reference-input field. The nominal for this value is zero and therefore is not req ired for entry. The tolerance band is unilateral; a negative tolerance is not displayed nor keyed in.

To use this tolerance, apply tide required tolerance, key in the basic angle, drag and drop the required features into the input fields and select APPLY.

Form — This selection suppli s access to circularity, flatness and straightness. The nominal for this value is zero and therefore is not x:71 required for entry. The tolera ce band is unilateral a negative tolerance is not displayed nor keyed in.

Form error can only be evalu best-fit features.

Coordinate — The coordinate tolerance allows the user to set tolerances on individual axes. The User may decide to print the locations of each feature along individual axes.

Coordinate tolerance reads the nominal location of the feature from the nominal definition. In the tolerance window, the nominal input field is unavailable for input. There are two methods available to edit nominal size and location data:

1. To edit the nominal value in the database area, RMB on the feature and select edit nominal. All the parameters defining the feature are available to edit in this window. Once the appropriate changes have been made, select APPLY in the lower right corner of the window.

2. The nominal values may be edited in the output window. Once the changes have been made, press 'Enter' to complete the input and then select the SAVE button at the top of the output window.

Run out — The run out tolera ce control is used when two features have a common datum axis. The revolution of one feature abo t the common axis defines a circular element that must be within the specified tolerance at any position. Run out controls only the circular elements of the surface, not the total surface. This tolerance is only available to circles. This tolerance requires the axis of the evaluation feature to be within five degrees of the reference feature.

Total run out — The total run put tolerance control is used when two features have a datum axis. The revolution of one feature about the common axis defines a cylindrical. Total run out is only available for planes and cylinders. The entire feature must be within the specified total run out common zone. Total run out controls the total surface of the feature. This tolerance requires the axis of the evaluation feature to be within five degrees of the reference feature.

Position — Position tolerance defines an area where the center of a feature of size is allowed to vary from the theoretical true position. Material conditions may be introduced to the datum features and the feature to which the tolerance applies. Nominal values are identified as basic dimensions on the print, and the nominal values must be applied to the target feature using one of the two methods described with the location tolerance se tion. To apply the material conditions to the datum features of the target feature, the size tolerance must e applied prior to the position tolerance.

Tolerance Tool Bar

Concentricity — Concentricity is defined using the median of all points on a feature of revolution and comparing them to the center point or axis of a datum feature. This tolerance requires the axis of the evaluation feature to be within one degree of the reference feature.

Symmetry — Symmetry is defined using the median of all points on two or more features with common locations. This tolerance has not been applied with Virtual DMIS version 2.0, but may be achieved using the distance between tolerance with a required nominal value of zero. The features evaluated with this tolerance must be reducible to a point.

Profp — (point profile) Profile of a point calculates the distance in three dimensions of the nominal feature to the actual feature. To use this tolerance, the nominal values of the point feature must be correct. In order to set up these nominal values, refer to the section on location tolerance. The nominal value will always be zero; this input field is unavailable to change.

Profile — (profile of stlirface or line) this tolerance requires nominal CAD data.

A nominal surface is aelected and scanned. The profile tolerance of the surface is evaluated. When working with the Surface option of Virtual DMIS, the error diagram will be displayed in a color-coded map of the actual surface.

A nominal curve is selected and scanned, and then the profile tolerance of the curve is evaluated. The evaluation will be displayed as a whisker diagram on the screen.

Select - allows the user to change to a previously defined sensor. Labels may be typed into the input field, or a sensor may be dragged and dropped from the ACTUAL or NOMINAL database area.

Change — allows the user to select any position available. The position change does not require a calibrated sensor. The new sensor positions are added to the nominal list of sensors in the sensor database. Nominal sensors may then be used for programming. Once the programming stage has been completed, the nomiral list of probes created, may be calibrated at one time. If the CMM is using motorized probe head, 672 probe positions are available during programming.

While working on an inspection piece, the user may measure a plane and drag and drop the plane into the Sensor Change window input field. When a plane is in the applet, the Perpendicular and Parallel Icons become relevant. Vi al DMIS will automatically select the position closest to perpendicular or parallel to the feature in the inp t Feature filed. 24

Define — This allows he user to define the sensor parameters. These parameters include sensor length, diameter, offset, tilt and rotation of the probe head. This is used to define a star stylus. This area also allows the user to ide Iffy parent/child relationships with the sensors. This parent child relationship is useful when using change racks and multi-tip sensors.

Calibrate- Calculates the size of the sensor being used. The window does not allow for manual entry of the sensor diameter nor the length. This routine will calibrate previously defined sensors. To calibrate, switch to the nominal sensor database and drag a nominal sensor into the input field. If the sensor was not previously defined, the slider bars allow the user to change the position of the sensor for calibration. This will create both nomirhal and actual sensors.

The MGAGE is a conlstant stored in the VMS.ini file. If a sphere other than the MGAGE is to be used for the calibration routine, simply drag and drop the sphere from the feature database, onto the picture of the sphere in the calibrati n window or into the drop down list box located just above the picture of the sphere. Once a new sphere i defined as the calibration sphere, the diameter will be displayed in the input field on the right of the pictur The nominal diameter of the sphere is a known value and is keyed in at this time. If the sphere has been easured, the system will allow the user to automatically calibrate the sensor by selecting the auto-measure icon in the measurement window.

Using Virtual DMIS

Mount — Is only necessary f r automatic systems. This window allows the user to define the position of the probe head in the quill. Horiz ntal arm CMMs allow the probe head to be placed in the quill in different orientations. In order to acco modate automatic probe calibration, the system must have the position of the probe head. The position is related to the machine coordinate system. The direction of a vector from the center of the probe head o the ruby of the stylus, defines the position. On a bridge machine, the red light is facing along the —Y-axis and the second vector is typically along the —Z-axis of the coordinate measuring machine. On a bridge machine, this icon may be removed from the tool bar.

Length and mount — Calculates the position of the probe head and the length of the sensor setup. This routine fine-tunes the orientation. The user will be prompted to measure two probe positions. The routine uses one position with the sensor at an angle of zero and a tilt of zero. The second position has the sensor at a tilt of ninety and rotation f zero degrees. There are no options for this routine. The calibration artifact may not be moved during thi routine. The program will warn the user that the sensor is about to change position; be sure to move the sensor clear of the artifact before selecting the OK button.

The sensor length and moun value is stored in the VMS.ini file. This calculation allows the User to use any position available, during pro ramming, prior to calibration of the required sensors.

NOTE: The Sensor Length and Mount routine provides the information required to execute automatic calibration. It is not necessa to run this routine unless there is a problem with the auto-cal. This is a DIAGNOSTIC TOOL for the ser.

Delete — When a sensor is d leted, it is removed from both the actual and nominal sensor lists.

Change rack set up — This r utine locates the TP200 change rack on the coordinate-measuring machine. The video supplied describes the use of this icon. This is only available if a TP200 system has been supplied with the machine. If there is no TP200 system, the icon will be grayed out and unavailable for use. In this situation, the icon may be removed from the sensor tool bar.

Sensor setting —Sensor settings control the parameters of the sensor movement throughout a program. These settings are changeable during the program. One of the first steps to a program should be to set up the sensor settings.

Senior Betting k These values are stored in the VMS.ini file and remain until they are changed within a program. There are six settings available in this window. Clicking the mouse over any one of the first five settings will play a short video clip describing the function of these settings.

Approach and Retract are also used to set the vector whisker length when using pick and meas offline.

Approach distance Defining the distance that the sensor will travel at a measure speed immediately prior to contacting th part. The machine will move at a normal move speed until the sensor reaches the location that is the a proach distance away from the nominal contact point. At this time the system will slow to the measure spee until the part is contacted or until the limit of the search distance is met.

Retract distance — Defines the distance that the sensor will travel at measure speed after the part has been contacted. Retr ct distance will be the set distance from the actual contact point of the sensor. This value may be disabl during joystick operation if programmable back off is selected in the following menu:

• System Tool Bar — Tools

• Machine Sta us

• Joystick

Refer to the section co pace 55 of this document.

Search distance —Defines how far the coordinate measuring machine will travel while trying to contact the part before presentin an error. The error is both an audio and an error window on the screen.

Depth — Depth of me surement describes the distance from the centroid that points will be taken while in auto-measure mode.

Example: During pro ramming, the program is set to auto-measure mode and a line is measured with 2 points 100mm apart he centroid of the line is at 0,50,0 (x, y, z). When this part of the program is rerun, the contacts will be at 0,48,0 and 0,52,0.

Clearance Surface — This setting causes the sensor to move along a diagonal path after the last point of a feature is taken to a point at the clearance surface setting above the first point of the next feature. If this feature is in use and outside features are being measured, the program may crash occasionally because the depth of the measurement and probe retract do not provide a clear path for the clearance surface move.

Clearance Feature — This s tting causes the sensor to move along the vector of the clearance feature to the distance of the clearance surface once the last point of a feature has been measured. The feature is usually a plane, and the mov ments supplied automatically with this feature greatly reduce the requirements for GOTO poin s.

SENSOR CALIBRATION

A sensor is calibrated because the computer does not automatically recognize manufacturing variations in the sensor installed n the system. There are dozens of combinations of length and size of sensors and hundreds of position available to calibrate. When the ruby of the sensor contacts a part, the computer is reading the center p int of the sensor. The system will then look at the calibration file and adjust the value for the size, length a d position of the sensor.

Sensor calibration al o checks for the sphere form error entered in the Systems settings and warnings tab, and gives an error w en the value entered is exceeded.

The VMS.ini file auto atically stores the sensor length and mount, when that routine is executed and the size of the sensor present. If the set up is not altered and programs are being created, and a graduated or automatic probe head is installed, it is not necessary to calibrate. If the sensor is undamaged, the values attained during programming will be accurate within a few microns. This error may be removed by calibrating the list of sensors created during programming.

While calibrating, it may be necessary to either move the MGAGE or use a different qualification artifact. In order to do this the al ernate sphere must be measured outside of the qualification routine. Then select the sensor calibration ico then drag and drop the alternate sphere label onto the picture of the sphere in the current window. The iameter of the sphere will automatically update to the current sphere.

AUTOMATIC PROBE HEADS

I Once a new sensor has been placed on the probe head, the nominal configurations must be

updated using the System Utilities Menu->Configuration->Sensor Configuration menu. This legacy icon it !lowed the system to run the sensor length and mount routine. This will copied the

length of the probe a sembly and the position of the probe head in the quill of the CMM to the VMS.ini file. This was only require when the sensor setup had been changed. It is no longer required if the sensor is properly defined.

41 I The next step is the calibration of the first sensor. The Default sensor is usually the first calibrated. Virtual DMIS upplies a position of 0,0 for a default sensor. Select the Sensors icon on the main

tool bar and the Sen or calibration icon on the Smart Tool Bar. The system will open a measurement window for MGAGE. The size of the MGAGE is traceable to N.I.S.T. standards in the United States and N.P.L. in the United Kingdom, and has been recorded in the VMS.ini file. If the size displayed in the calibration window is not correct, simply type in the correct value. Once the MGAGE has been used one time to calibrate the sensor, the subsequent calibrations may be preformed automatically.

To calibrate a second sensor at, use the slider bars in the sensor calibration window to change the position

Axis performs 2 functions. When Axis is selected, the rotation will be in 3 dimensions, causing the 3D vector of the feature to be the primary axis of the coordinate system. Planes, Cylinders and Cones are used for the primary vector of a coordinate system. The direction of the primary axis is set using the Dir selection. When a primary axis is created, the origin is translated to that feature as well. In the example above, the Z origin would be set at PL5.

When X-axis, Y-axis or Z-axis is selected, the rotation will be 2D rotating about the previously set primary axis. For example, if the appl button was selected in the window above, the Primary Axis would be perpendicular PL5 the axis wo uld represent Z+. The next step is to enter a feature with direction and the DIR selection would be either X or Y and the AXIS selection the Z-axis (the previously set primary axis).

The second function is to send any text in the text window, of the output window, directly to the output device and report file.

Virtual DMIS works with the installed printer and displays one page at a time as it is stored on the printer buffer.

This allows the user to send data to a printer that is not currently the system default printer. In order to force the change to take effect, Virtual DMIS must be exited then restarted.

Output Bitmap This icon causes the Windows File Open dialogue window to open. Once opened the user may navigate through the directories to select a previously stored bitmap image to be se nt to the output report.

HINT: It is always easier for the user if the pictures are stored in a simple directory path. For example: C:\pics\mypic.bmp

Clear All This wil erase any data currently residing on the printer buffer.

View Output file This wit cause Notepad to open the current report file. Virtual DMIS by default generates "DEFAULT.REP". In order to change the file name before storing data in the file, the user must go to the output settings and LMB on Select A New File.

The user may view a file and edit the file if required. When the file is closed, the user will be prompted to save any changes, only if changes were performed.

an acronym for Dimensional Measurement Interface Standard. This is an standard. It is a standardized language communicates programming commands

a CMM. DMIS allows CMM programs to be portable between CMM manufacturers. example, an inspection program generated with Virtual DMIS may run on any CMM

with DMIS capabilities.

order to purchase a copy of the DMIS standard, contact the Consortium for Manufacturing- International CAM-I . Although the standard is not required

programming through the Virtual DMIS user Interface, it may become necessary as learn more about the DMIS language and want to implement some of the

functions into the Virtual DMIS programs.

DRIVER

ERROR MAP An error map is generated when a CMM Service technician calibrates the CMM. The error map mathematically corrects linear length, machine squareness, roll, pitch and yaw of the machine structure. Once generated, the Error map must be loaded before the CMM can be used for measurement.

FEATURE A general term used to discuss basic geometrical items.

HOME — Home position is typically at the extreme left, front upper corner of the travel of the CMM. The position is controlled by the VMS.ini file.

PTB CERT Virtual DMIS has been certified by the Physikalisch -Technische Bundesanstalt. It is the national institute of natural and engineering sciences. PTB is the highest technical authority for metrology and physical safety engineering of the Federal Republic of Germany

TOLERANCE Home position on a CMM indicates a predefined location where the CMM is moved to for the error map to be loaded. If the CMM is not loaded error map corrections are made to the wrong area of the CMM.
