Programming example

Determination of coordinates of the corner of a workpiece with subsequent ZO offset
The coordinates of the corner of a workpiece are to be determined by outside measurement.
ZO G55 must be corrected in such a way that the corner point is workpiece zero when G55
is selected.
Measurement is performed in plane G17 with active G54. The values in mm of the
coordinates of points P1...P4 from which the workpiece can be approached parallel to the
axis are:
• P1.x=50
• P2.x=150
• P3.x=15
• P4.x=15
The probe is to be positioned at a height of 100 mm. The measuring depth is 60 mm lower.
