You can use the Shift (mW-CS) function to compensate for an offset relative to the workpiece preset for a reworking operation where probing is difficult in the modified workpiece coordinate system mW-CS, for example.
Application
Description of function
The Shift (mW-CS) function acts on an axis-by-axis basis. The value is added to an existing shift in the W-CS workpiece coordinate system.
Workpiece coordinate system W-CS
The Shift (mW-CS) function affects the position display. The control shifts the display by the active value.
A modified workpiece coordinate system mW-CS is present with active Shift (W-CS) or active Mirroring (W-CS). Without these preceding coordinate transformations, the Shift (mW-CS) option would be effective directly in the workpiece coordinate system (W-CS) and would thus be identical to Shift (W-CS).
Application example
You mirror the CAM output of an NC program. After mirroring, you shift the workpiece datum in the mirrored coordinate system to produce the counterpart to a mirror cap.
- Initial situation:
- Available CAM output for right mirror cap
- The workpiece datum is located in the left front corner of the workpiece blank.
- NC program set to the center of the ball-nose cutter and Function TCPM function with spatial angles output
- The left mirror cap is to be machined
