Mastercam X5 Home Learning Edition DVD

The Mastercam X5 Home Learning Edition is a demo that provides a fully functional* version of Mastercam that

can be installed on your home PC. The software must be re-installed after 6 months and expires completely

October 31st, 2012.

*All Mastercam modules are available; however, there are a few limitations such as no support for C-Hooks and

limitations around post processing.

Mill Level 1 Training CD

The Mill Level 1 Training CD is an excellent resource for beginners and experienced users alike. For new users, we

have created a video called "Mastercam Worksapce" which serves as an introduction to the Mastercam user

interface.

Video training exercises complement the book by teaching the fundamentals of 2D geometry creation. These are

interactive exercises where we provide .MCX-5 files so you can do each exercise with video instruction. Werecommend that beginners complete the training exercises prior to starting the book.

We have included an additional chapter called "General Notes" that provides useful tools, shortcuts and toolpath

parameter descriptions in a PDF file.

In addition, there are complete step-by-step videos for each of the tutorials in the book.

TUTORIAL #31

TUTORIAL #3

Objectives:

The Student will design a 2-dimensional drawing by:

Create arcs polar knowing the diameter, location, start and end angles.

Create parallel lines, by defining the offset direction and distance.

Create fillets knowing the radius size.

Create lines on an angle knowing the starting point and angle.

Mirror the part to create the other 1/2 of the part.

The Student will create toolpaths consisting of two setups:

An open pocket toolpath to remove the material in the open area.

Contour remachining toolpath to cut the material which the open pocket left.

A circle mill toolpath to remove the material in the arc.

Three drill toolpaths to, spot drill, drill and tap the holes.

A contour toolpath to remove the material at the parts exterior.

The contour toolpath will be part of setup #2.

The Student will simulate the toolpaths using Mastercam's Verify and Backplot by:

Defining a 3-dimensional rectangular block the size of the workpiece.

Running the Backplot to see the path the tool takes to cut the part.

Running the Verify to simulate the tool cutting from a solid model.

This tutorial takes approximately one hour to complete.

SETTING UP THE GRAPHIC USER INTERFACE TUTORIAL #31

GEOMETRY CREATION

STEP 1: SETTING UP THE GRAPHIC USER INTERFACE

Before starting the geometry creation we should customize the toolbars to see the toolbars

required to create the geometry and machine a 2D part. See Getting startedpage A-4 for

details.

Make sure that the Grid is enabled. It will show you where the part origin is. See Getting

startedpage A-6 for further information.

TheOperations Managerto the left of the screen can be hidden to gain more space in thegraphic area for design. From the keyboard, press Alt + Okeys simultaneously to hide it. Repeat

this command to make it visible again.

SELECT THE MACHINE AND SET UP THE STOCK TUTORIAL #31

STEP 13: SELECT THE MACHINE AND SET UP THE STOCK

In Mastercam, you select a Machine Definition before creating any toolpaths. The Machine Definition is

a model of your machines capabilities and features. It acts like a template for setting up your machine.

The machine definition ties together three main components. The schematic model of your machines

components. The control definition that models your control capabilities and the post processor that will

generate the required machine code (G-code). For a Mill Level 1 exercise (2D toolpaths) we need just a

basic machine definition.

To display the Operations Manager press Alt + O.


Machine type Mill.

Default.

Select the plus sign in front ofProperties in the ToolpathsManager to expand the Toolpaths

Group Properties.

NOTE: For the purpose of this tutorial, we will be using the Default milling machine.

Program # is used to enter a number if your

machine tool requires a number for a

program name.

Assign tool numbers sequentially allows

youto overwrite the tool number from thelibrary with the next available tool number

(First operation tool number 1; Second

operation tool number 2, etc.).

Warn of duplicate tool numbers allows you

to get a warning if you enter two tools with

the same number.

Override defaultswith modal values

enables the system to keep the values that

you enter.

Feed Calculation set From tool uses feedrate, plunge rate, retract rate and spindle

speed from the tool definition.

Display options allow you to set the stock

as Wireframe and to fit the stock to the

screen (Fit Screen).

NOTE: The stock model that you create can be displayed with the part geometry whenviewing the file or the toolpaths, during backplot, or while verifying toolpaths. In the

graphics, the plus shows you where the stock origin is. The default position is the middle of

the stock. Click on the corner of the part to set it as the stock origin.

STEP 18: CIRCLE MILL THE LARGE HOLE

Circle mill toolpath is used to mill circular pockets based on a single point. Mastercam will pocket out a

circular area of the diameter and to the depth that you specify. After milling the center of the circle,

Mastercam calculates an entry arc before approaching the perimeter and then a similar exit arc. You can

add enhancements such as multiple passes, multiple depth cuts and helical plunge moves as well fine

tuning the entry and exit arcs.

Helical entry creates a helix at the center of the circle to begin the roughing motion.

Output arc moves writes the entry helix to the NCI file as arcs. Use this option to create shorter NC files. If this option is

off the helix is turned into linear segments.

CREATING AND RENAMING TOOLPATH GROUPS TUTORIAL #31

STEP 22: CREATING AND RENAMING TOOLPATH GROUPS

To machine the part in two different setups, we will need to have two separate programs. To be able to

post process separately the operations of each setup, we will create them under different toolpath

groups with different NC names.

22.1 Rename the current Toolpath Group - 1 and NC file

Click two times on the Toolpath Group - 1 to highlight it and rename it "Setup #1" as shown

in Figure: 22.1.1.

Figure: 22.1.1

Right mouse click on the toolpath group and select Edit selected operations and then, select

Select the OK button to accept the new NC name.

Create a new Toolpath Group.

Right mouse click on the Setup #1 and hold the mouse button down.

Drag the cursor below the insert arrow and select Copy After. Thiswill create a new toolpath

group and copy the toolpaths below.

At this time with the toolpaths selected press Delete on your keyboard.

A message will pop up asking you if you want to delete the toolpaths.

Select Yes from this message. Rename the toolpath group "Setup #2".
