Holes Or 2 Circular Spigots - Siemens SINUMERIK 840D sl Programming Manual

4.2.5.3

2 holes or 2 circular spigots

This permits calculation of the basic rotation (rotation in the working plane) of the clamped
workpiece.
This enables orientation by:
• "Coordinate rotation" or
• rotation of the workpiece with a rotary table (rotary axis).
For an angle offset by "coordinate rotation", it is possible to set the reference point for the
calculated center of the 1st hole/spigot.
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, for a hole to measuring depth in
each case, for a spigot above the spigot.
