Function Shift (W-CS)

Application

You can use the Shift (W-CS) function to compensate for an offset relative to the workpiece preset for a reworking operation where probing is difficult, for example.

Description of function

The Shift (W-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 (W-CS) function affects the position display. The control shifts the display by the active value.

Application example

The surface of a workpiece to be reworked is determined using the handwheel and the offset is compensated for using the Shift (W-CS) function.

  • Initial situation:
  • Reworking of a free-form surface is required
  • Workpiece clamped
  • Basic rotation and workpiece preset measured in the working plane
  • Z coordinate must be defined with the handwheel due to the presence of a free-form surface
  1. To shift the workpiece surface of a workpiece to be reworked:
  2. Open the GS workspace
  3. Activate the Handwheel superimp. toggle switch
  4. Determine the workpiece surface by scratching, using the handwheel
  5. Activate the Shift (W-CS) toggle switch
  6. Transfer the determined value to the corresponding axis of the Shift (W-CS) function (e.g. Z)

  1. Press Apply

  1. Start an NC program
  2. Activate Handwheel superimp. with the Workpiece (WPL-CS) coordinate system
  3. Determine the workpiece surface by scratching, using the handwheel for fine adjustment

  1. Select NC program
  2. The control takes the Shift (W-CS) into account.
  3. The control uses the current values from Handwheel superimp. in the Workpiece (WPL-CS) coordinate system.
