Calibrate probe - calibrate in groove (CYCLE973)

Function
Only applies on turning machines without the milling technology.
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 sphere 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 sphere 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 sphere diameter. The trigger points always
refer to the center of the probe sphere (TCP).
The probe moves in the selected measuring axis in both directions in the calibration groove.

Requirements
● The workpiece probe must be called as tool with the associated tool offset.
● The machine-related geometrical dimensions of the selected calibration group must be
saved before calibration in the corresponding general setting data.
