Calibrate probe - calibrate in groove (CYCLE973)

Function
Using this measuring version, a workpiece probe with cutting edge position SL=7 or SL=8
can be calibrated in a reference groove machine-related in the axes of the plane. The
measuring probe length or the probe ball radius can be determined with the calibration.
With the radius determination, a calibration is possible in one direction or in opposite
directions of an axis. It is also possible to determine the positional deviation (skew) of the
probe and the effective diameter of the probe ball during calibration in opposite directions.
Measuring principle
The measured switching positions of the workpiece probe in the parameterized axis are
taken into account together with the machine-related data of the selected calibration groove.
From this data, the trigger points are calculated in the positive and negative directions as
well as the position deviation in this axis and the effective probe ball diameter. The trigger
points always refer to the center of the probe ball (TCP).
The probe moves in the selected measuring axis in both directions in the calibration groove.
