Preconditions
Note
The tool probe must be calibrated before the tool measurement (see Calibrate probe
(CYCLE971) (Page 202)).
● The tool geometry data (approximate values) must be entered in a tool offset data set.
● The tool must be active.
● The machining plane must be programmed in which the probe was calibrated.
● The tool must be prepositioned in such as way that collision-free approach with the probe
Starting position before the measurement
Before the cycle call, a starting position must be assumed from which the probe can be
approached collision-free. The measuring cycle calculates the direction of approach and
generates the appropriate traversing blocks.
