Programming example

Calibrating a workpiece probe in the X-Y plane, unknown hole center point
Workpiece probe 2, used as tool T10, D1, is to be recalibrated in a hole with D=110.246 mm
and not precisely known center point (CP) in axes X and Y in both axis directions with G17
and paraxially (to redetermine trigger values _WP[i,1] to _WP[i,4].
The positional deviation (skew _WP[i,7], _WP[i,8]) and precise ball diameter _WP[i,0] of the
probe is also to be ascertained.
