CYCLE978 workpiece: Measuring a surface parallel to the axis

Function overview

Function
This measuring cycle determines the position of a paraxial surface in the workpiece
coordinate system. This is done with 1-point measurement
On the basis of the measuring results and depending on the measuring variant selected,
• automatic tool compensation can also be undertaken for a tool or
• a zero offset (ZO) can also be corrected.
A special measuring variant permits differential measurement with the axes of the plane. The
special procedure for this measurement permits use of an uncalibrated multidirectional
probe.
Workpiece probe types that can be used
• Multidirectional probe (_PRNUM=0xy)
• Monodirectional, bidirectional probe (_PRNUM=1xy)

(These probes should be used only with low accuracy requirements!)
Notice
A monodirectional or bi-directional probe must always be calibrated! These probes
cannot be used for the differential measurement!
