Function Shift (mW-CS)

Application

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.

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.

Position displays

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
  1. To shift the datum in the mirrored coordinate system:
  2. Open the GS workspace
  3. Activate the Mirroring (W-CS) toggle switch
  4. Activate the X toggle switch
  5. Activate the Shift (mW-CS) toggle switch
  6. Enter the value for shifting the workpiece datum in the mirrored coordinate system

  1. Press Apply

  1. Run the NC program
  2. The control takes the Mirroring (W-CS) value for the X axis and the required rotary axes into account.
  3. The control takes the modified position of the workpiece datum into account.
