Measuring Cycles for Milling and Machining Centers
5.8 CYCLE961 workpiece: Setup inside and outside corner
Compensation of the zero offset
The ZO correction is applied in the coarse offset. If a fine offset is available (MD18600:
MM_FRAME_FINE_TRANS=1), it is reset.
If _KNUM=0, there is no zero offset (ZO).
When _KNUM 0, the corresponding ZO for the abscissa and ordinate is calculated in such a
way that the calculated corner point becomes the workpiece zero. The rotary component for
the applicate (rotation about Z for G17) is offset in such a way that the workpiece coordinate
system lies in the plane parallel to the reference edge.
Workpiece measuring probe type that can be used
Multidirectional probe (_PRNUM=xy)
NOTICE
Precise measurement is only possible with a probe calibrated under the measurement
conditions, i.e. working plane, orientation of the spindle in the plane and measuring velocity
are the same for both measurement and calibration. Deviations can cause additional
measuring errors.
