Explanation of example
The cycle automatically approaches reference groove 1 from the starting position and
performs calibration in both axes and in the X axis in a double cycle call. The new trigger
values are stored in the data of the workpiece probe 1 _WP[0,1], _WP[0,3], _WP[0,4].
At the end, result array _OVR[ ] contains the values of the 2nd cycle call.

Operational sequence

Position before measuring cycle call
The starting point must be selected such that the selected workpiece probe can be
positioned in the cycle into the reference groove selected via _CALNUM by the shortest path
with paraxial collision-free movements in accordance with the active cutting edge position.
Position after end of measuring cycle
On completion of calibration, the probe is positioned facing the calibration surface at
distance _FA.

Calibration on surface

6.4.3.1

General information

Function
With this measuring cycle and the _MVAR=0 measuring variant, it is possible to calibrate a
workpiece probe with cutting edge positions SL=5 to 8 on a surface (workpiece-related) and
therefore determine the probe trigger points.
