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.
