This operating manual intends to facilitate the installation and the configuration of the tool change system STG104 / WZW104.

It focuses primarily on the interaction with our High-Z and RaptorX-SL machines and the software WinPCNC Professional.

Further details can be found in the tool change system and control software WinPCNC manuals!

Technical Description This tool change system enables the automatic tool change in milling programs which have to work with different tools. In combination with a tool-length sensor the automatic tool length compensation can be used to adjust the differences in length of the tools.

Requirements for the use of the change system

- Milling Machine Type High-Z or RaptorX-SL - Control Unit STG104 with tool changer WZW104 - Tool Change Magazine (optionally with tool-length sensor) - Software WinPCNC Professional with axis controller and I/O card - Compressed-air supply or compressor with a working pressure of at least 8

bar

Connecting the Control Unit STG104

The control unit is connected with our axis controller (CNCCON S) via the supplied 15-pole connection cable.

The connecting of the tool change spindle and the pneumatic components is described in the separate manual.

Mounting of the Spindle and the Tool Magazine

The tool change spindle is inserted into the 43mm tool holder of our milling machine and tightened lightly .

The connection cable and air tubes must be laid carefully so that they can’t get jammed or damaged when the machine is moving!

Tool Magazines

Dust-protected, pneumatic 6 tool magazine (WZM 6 tool magazine) with integrated tool-length sensor for tool holders SK15

5 tool magazine for tool holders SK15 The tool magazine has to be installed within the

travelling area at right angles to the machine geometry. The position is freely selectable depending on the application and needs. Connecting the Tool Magazine WZM 6 : The pneumatically operated protection cover must be connected to the control unit by air tube. (See manual) The integrated tool-length sensor is connected to the machine via a 3.5mm jack plug. The jack socket is below the connection box with the emergency stop switch.

The connection cable and air tube must be laid carefully so that they can’t get jammed or damaged when the machine is moving!

Now, the tool change system is connected insofar as the manual operation via the control unit STG 104 is possible. (See manual)

Control via the WinPCNC Professional software We already have done the connection to the axis controller and therefore to the PC via the 15-pole connection cable. But in order to control the tool change system comfortably via the software some adjustments need to be made. All necessary adjustments are done in WinPCNC Professional. Enable tool change function:

Under parameter machine functions The following functions must be checked: „ Enable Macros“, „Automatic Tool changer“, „Length measurement and compensation“ Save settings! Afterwards the software must be restarted! Under parameter machine others At tool change enter „Yes, use ATC“! Save settings!

R.Ehren / 22.11.2010 - Rev.1.0 Seite 5


Signal Assignment Now, the input and output signals for controlling the tool change system must be assigned in the software. The following output signals must be assigned:

Output Pin assignment Function Q242 spindle EA15 pin9 Spindle on/off Q248 Mollet EA15 pin13 Mollet open/close Q100 exit M70 EA15 pin10 Magazine protection cover The following input signals must be assigned:

Input Pin assignment Function

I221 sensor LPT pin15 Tool-length sensor

EA15 stands for expansion port at the axis controller 15 pin. LPT connection cable LPT-interface 25pin.

Under parameter machine signals the signals must be assigned! For this you mark the desired line with the mouse and select the desired pin in the drop-down box (e.g. LPT pin 15) Then click on “apply”. After assignment of all pins: Save settings!

Inverting of signal pins:

By inverting the signal pins the circuit logic can be reversed. Non used reference switches or non active switches/sensors should be marked black in signal test! Activated switches/sensors are marked red. If a non used input is marked red one can correct this by inverting the signal pin! (e.g. LPT pin 15 inv)

Specify position of the tool magazine In the first step you need to run up to the position of the first tool rest position (stopping point). For this the spindle must be driven slowly and manually over the first rest position, as centrally as possible. (The spindle must be positioned as accurately as possible – best work in twos!) Now, the spindle must be lowered with the Mollet open. The ideal stopping point is about 2-5mm before the spindle touches the tool. Write down the determined values for X, Y and Z!

Under parameter tools changer the tool positions must be entered. The previously determined values for X and Y of the first tool (stopping point) are entered here. The Z-value for all tools should be “0”.

If the magazine is mounted right-angled to the machine as described, the positions of the remaining tools can be calculated. Note: When using the “WZM 6 tool magazine “ the stopping point should be moved so that the protection cover can open without the risk of damaging the tool! (e.g. X +50mm). Add this distance to the tool position above.

R.Ehren / 22.11.2010 - Rev.1.0 Seite 7


Specify position of the tool-length sensor (Surface block) Manually move to the position of the tool-length senor, as centrally as possible. Write down the position values for X and Y! For the “WZW 6 tool magazine “, the position can also be determined based on the above drawing.

Under parameter tools length The Surface Block sensor positions must be entered. Under parameter tools length The sensor positions (stopping point) must be entered. The Z-value should be “0”! When using the “WZM 6 tool magazine“ the stopping point should be moved so that the

protection cover can open without the risk of damaging the tool! (e.g. X +30mm) In addition, the “automatic tool length compensation” should be activated so that the differences in lengths of the tools can be taken into account by the programme. The “length measurement after change” ensures a testing of the tool length after each tool change. The “Fast move to sensor with brake” causes a faster start-up of the sensor and should be deactivated! This may only be applied in combination with length sensors which are especially designed for this purpose!!! Otherwise the sensor or the tool can be damaged. The option “Z-Zero-Point recalculate“ resets the Z-zero-point after each length measurement. The program defines the zero-point based on the current tool so

that one has the correct Z-value also if driven manually. Otherwise, this is done automatically during a job. Starting position The use of the tool change spindle in combination with the tool magazine “WZM 6 tool magazine” with integrated length sensor serves as an example of the programming. As described before the starting point is then the following:

As a reminder: The stopping position of the spindle next to the tool magazine is chosen because of the opening of the protection cover. On the following pages the macros for the tool change procedure must be programmed!

R.Ehren / 22.11.2010 - Rev.1.0 Seite 9


Programming the tool change process using macros The adjustment of the tool change process can be controlled by the macros. Under parameter tools macros

are several macros available. “Deactivate Macros” causes a temporary deactivation of the macro function.

Macro „before tool change“ Here, the opening of the protection cover can be programmed in combination with the magazine „WZM 6 tool magazine“. We had assigned the output signal Q100 to the protection cover (see under signals).

To open the protection cover the macro “SetOutputHigh” must be chosen out of the list and assigned to the desired output (NB! Value - 100). To apply settings the button “Insert” must be clicked and the macro must be saved afterwards! Macro „after tool change“

Here, the closing of the protection cover can be programmed in combination with the magazine „WZM 6 tool magazine“. We had assigned the output signal Q100 to the protection cover (see under signals).

R.Ehren / 22.11.2010 - Rev.1.0 Seite 10


To close the protection cover the macro “ResetSetOutput” must be chosen out of the list and assigned to the desired output (NB! Value-100). To apply settings the button “Insert” must be clicked and the macro must be saved afterwards! Macro „before tool length check“

In combination with the magazine “WZM 6 tool magazine” the protection cover must be opened before the measuring process. We had assigned the output signal Q100 to the protection cover (see under signals). To open the protection cover the macro “SetOutput” must be chosen out of the list and assigned to the desired output (NB! Value for SetOutput = 100).

Then the spindle must be driven from the stopping position (X=50 / Y=37.5) over the sensor (X=20 / Y=37.5). For that we choose the macro “MoveX” and enter -30,000 accordingly. To apply settings the button “Insert” must be clicked and the macro must be saved afterwards!

Macro „after tool length check “ In combination with the magazine “WZM 6 tool magazine” the protection cover must be closed before the measuring process. We had assigned the output signal Q100 to the protection cover (see under signals). The Macro „before measuring“ must be in the reverse order. The spindle must be driven from the sensor position (X=20 / Y=37.5) back to the stopping position (X=50 / Y=37.5). For that we choose the macro “MoveX” and enter -30,000 accordingly. To close the protection cover the macro “ResetOutput” must be chosen out of the list and assigned to the desired output (NB! Value for ResetOutput = 100).

To apply settings the button “Insert” must be clicked and the macro must be saved afterwards!

Macro „ATC Grab“ This macro is used to pick up a new tool. How to select macros and assign the corresponding values has already been explained.

Macro to pick up the tool “ATC Grab”: MolletOpen Opens of the Mollet Wait 1000 Waiting period in milliseconds until the next step The Mollet needs time to open Speed 70 Here, the traverse speed can be set

If nothing is specified, the speed will be taken from the machine parameters

MoveX -50 The spindle drives from the stopping position (X=80) to the changing position (X=30)

MoveZ +80 The spindle drives to the correct Z depth to pick up the tool (this value was determined at the beginning)

MolletClose Causes the closing of the Mollet Wait 1000 Waiting period in milliseconds until the next step The mollet needs time to close MoveX -80 The spindle drives up again MoveX +50 The spindle drives from the changing position (X=30) back

to the stopping position (X=80) This is only an example and can be customized according to your needs.

Macro „ATC Release“ This macro is used to put down a tool. How to select macros and assign the corresponding values has already been explained.

Macro to put down the tool “ATC Release”: Speed 70 Here, the traverse speed can be set

If nothing is specified, the speed will be taken out of the machine parameters

MoveX -50 The spindle drives from the stopping position (X=80) to the changing position (X=30)

MoveZ +80 The spindle drives to the depth-position to put down the tool (this value was determined at the beginning!)

MolletOpen Causes the opening of the Mollet Wait 1000 Waiting period in milliseconds until the next step The Mollet needs time to open MoveX -80 The spindle drives up again MoveX +50 The spindle drives from the changing position (X=30) back

to the stopping position (X=80) This is a working example but can be customized according to your needs.
