5.6 CYCLE979 workpiece: Measure hole/shaft/groove/rib at an angle
Position at end of measuring cycle
At the end of the measuring cycle, the probe (ball circumference) is distance _FA (path) from
the last measuring point (setpoint) at measuring height.

Measuring and tool offset

5.6.3.1

General information

Function
Using this measuring cycle and various _MVAR=1...4measurement variants, the contour
elements hole, shaft, groove, web, can be measured at an angle.
Automatic tool offset is also possible. This tool is specified in _TNUM and _TNAME. The D
number and type of offset are specified in coded form in variable _KNUM.
With an extended tool offset, a tool from a particular stored tool environment _TENV, and
additive or setup offsets can be corrected by specifying the DL number in _DLNUM.
Detailed information on the parameters: see the Parameter description section "Description
of the most important defining parameters".
