Post Process : GPP2 - Post Dialog > Machine Parameters

Access: Open this function from one of the following locations:

  • Select NC Process > Post & Report > Post Process from the menu bar.

  • Click the Post Process button in the NC Guide.

  • Click the Post Process button in the Job Manager.

  • Right-click on an item in the Process Manager, or anywhere in the graphics window when no procedure is active, and select NC Guide Commands > Post Process from the popup menu.

Set the GPP2 machine parameters.

In the GPP2 - Post Dialog, click the Machine Parameters button:

The Machine Parameters dialog is displayed.
- Set the Home Parameters
- Set the Machine Simulation Data

UCS List

Define a name in the output file for each UCS.

Setup Zero Position

This field displays the settings as defined in the NC Setup; this can be changed if required.

The numbers displayed here represent the position of the part (to be machined) on the machining center, relative to a predefined UCS. You can modify the offset values to adjust the part location within the machine envelope, enabling optimal use of the available space.

Define the XYZ machine zero in the coordinate system, either by directly entering the XYZ coordinates or by using the adjacent button to pick a point on the screen (the XYZ coordinates of the selected point are displayed). This results in a re-calculation of the position of the part relative to the machine zero point.

The coordinates are passed to the Post Processor in the BEGINNING OF TAPE block (X_MACH, Y_MACH, Z_MACH).

  • In GPP posts (where the Reference UCS is not defined), the vector from the clicked point to the MODEL UCS zero is calculated and expressed in MACSYS UCS terms.

  • In GPP2 posts (where the Reference UCS exists), the vector from the clicked point to the REF UCS origin is calculated and expressed in Reference UCS terms.

This definition is needed for Machining Simulation, but also affects the actual G-Code if being used by the specific post processor.

Modifying the Reference UCS at any point (or switching between a GPP post processor to a GPP2 post processor) does not affect the numbers. Once calculated (or keyed in), they stay "as is".

For GPP2, setting the displayed numbers at (0,0,0) effectively tells GPP2 to ignore them (since it means that the machine zero point is at the REF UCS zero point). This is equivalent to setting M5_USE_MACH (5X machine definition variable) to FALSE inside the post processor.

 

Machine Parameters > Machine Simulation Data

The GPP2 Machine Simulation Data parameters are identical to some of the parameters of the Machining Simulation dialog.

See the Machining Simulation Material Removal and Check Against Part parameter explanations.

Note: Recommended for TP Tolerance: If you are only posting a Finish toolpath, use the tolerance of the least "tight" tolerance of all the Finish procedures that touch the part with an offset of zero.
