Holes Or 4 Circular Spigots - Siemens SINUMERIK 840D sl Programming Manual

4.2.5.5

4 holes or 4 circular spigots

This permits calculation of the reference point P0 and the "alpha" rotation of the clamped
workpiece.
This permits orientation by coordinate rotation and setting point P0 (intersection point of the
2 straight lines, whose hole centers are connected diagonally) as the reference point.
Measurement is performed in both axes of the working plane.
Approaching the workpiece
Position the probe roughly in the center of the 1st hole/spigot P1, after completion of this
measurement in the rough center of the 2nd hole/spigot P2, etc., for a hole to measuring
depth in each case, for a spigot above the spigot.

Under the "set angle" input, an orientation deviating from 0 degrees with respect to the
1st axis of the working plane (e.g., G17: X axis) is possible.
