Workpiece measurement

With this function it is possible to determine the workpiece zero offsets using a workpiece
probe in the machine. The resulting zero offsets are automatically loaded in the zero offset
memories G54 to G57.
The zero offset memory G58/G59 and the external zero offset cannot be loaded with this
function.
Prerequisites
• The reference points have been approached.
• The starting conditions for automatic mode are fulfilled.
• The workpiece probe is in the turret or the spindle.
• The workpiece probe has been calibrated with measuring cycle L973/L976.
• Plane correctly defined, initial setting.
