2.12 Online tool length offset
Functionality
Effective tool length can be changed in real time so that the length changes are also considered
for changes in orientation of the tool. The system variable $AA_TOFF[<geometry axis name>]
includes tool length compensations in 3-D according to the three tool directions.
None of the tool parameters are changed. The actual compensation is performed internally by
means of transformations using an orientable tool length compensation.
The number of active compensation directions must be the same as the number of active
geometry axes. All offsets can be active at the same time.
