Right-angled corner

This permits measurement of a right-angled corner of a workpiece as the reference point in
the axes of the working plane and setting it as the ZO (translation and rotation).
3 measuring points are required: P1, P2, and P3.
The 1st axis of the working plane functions as the reference axis (for G17: X axis). Edge P1,
P2 functions as the reference edge on the workpiece. This edge is aligned parallel to the
reference axis (G17: X axis).
Approaching the workpiece
Position the probe on the corner, first at P1 and after completion of this measurement at P2,
and after completion of this measurement at P3 - to measuring depth in each case.

• Select of the ZO
• Select outside or inside corner
• Select the position of the corner
• Enter the set position required for the reference point P0 (corner) for the selected ZO in
Result
Measurement is performed automatically at P1 with the set measuring feed as soon as you
press "NC Start". Measurement is performed in the axis and axis direction determined by the
selected position. After successful measurement, the previously inactive softkey "P1 stored"
is activated and the coordinates of the 1st measuring point P1 is stored internally.
After manual positioning in front of the 2nd measuring point P2, measuring is performed
automatically at this measuring point on pressing "NC start". Proceed in the same way for
measuring point P3.
If all of the measuring points have been successfully completed and all "Px saved" softkeys
activated, then a vertical "calculate" softkey is displayed. After this softkey has been
pressed, the corner coordinates P0 and the offset are calculated. The offset is activated at
the same time if it is the active ZO.
