The Shift (W-CS) function

Application

You may use the Shift (W-CS) function to, for example, rework in order to compensate for the relative offset of a position that is difficult to probe and the workpiece datum.

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

To shift the workpiece surface of a workpiece to be reworked:

  1. Open the GPS workspace
  2. Activate the Handwheel superimp. switch
  3. Determine the workpiece surface by scratching, using the handwheel
  4. Activate the Shift (W-CS) toggle switch
  5. 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.
