Function Additive offset (M-CS)

Application

With the Additive offset (M-CS) function, you can shift the zero position of a machine axis in the machine coordinate system M-CS. You can use this function, for example, on large machines, to compensate an axis when using axis angles.

Description of function

The control adds the value to the active axis-specific offset from the preset table.

Preset table

If you activate a value in the Additive offset (M-CS) function, the zero position of the affected axis changes in the position display of the Positions workspace. The control assumes a different zero position of the axes.

Application example

The travel range of a machine with AC fork head is increased using the Additive offset (M-CS) function. An eccentric tool chuck is used and the zero position of the C axis is shifted by 180°.

  • Initial situation:
  • Machine kinematics with AC fork head
  • Use of an eccentric tool chuck
  • The tool is clamped in an eccentric tool chuck outside the center of rotation of the C axis.

  • The machine parameter presetToAlignAxis (no. 300203) for the C axis is set to FALSE
  1. To increase the traversing distance:
  2. Open the GS workspace
  3. Activate the Additive offset (M-CS) toggle switch
  4. Enter C 180°

  1. Press Apply

  1. Program a positioning movement with L C+0 in the desired NC program
  2. Select an NC program
  3. The control considers the 180° rotation for all C axis positioning movements as well as the changed tool position.
  4. The position of the C axis does not affect the position of the workpiece preset.
