Calibrating in the reference groove

6.4.2.1

General information

Function
With this measuring cycle and the _MVAR=xxx13 measuring variant, it is possible to
calibrate a workpiece probe with cutting edge position SL=7 or SL=8 in a reference groove
machine-related in the axes of the plane (abscissa, ordinate).
Calibration is possible in one direction (_MVAR=x1x13) or in both directions of an axis
(_MVAR=x2x13).
It is also possible to calibrate the position deviation of the probe and the active diameter of
the probe ball in both directions.
The workpiece probe calibrated is selected with _PRNUM. The associated array _WP[ ] in
data block GUD6.DEF is _WP[_PRNUM-1,...] (for a detailed description of the array, refer to
Chapter "Data description", "Central values").
The reference groove is selected with _CALNUM. The associated array _KB[ ] in data block
GUD6.DEF is _KB[_CALNUM-1,...].
