undamentals
16.1 Fundamentals
Overview
The TNC offers twelve cycles for measuring workpieces
automatically.
Danger of collision!
When running touch probe cycles, no cycles must be
active for coordinate transformation (Cycle 7 DATUM,
Cycle 8 MIRROR IMAGE, Cycle 10 ROTATION, Cycles 11
and 26 SCALING and Cycle 19 WORKING PLANE or 3D-
ROT).
The TNC must be specially prepared by the machine tool
builder for the use of a 3-D touch probe.
The touch probe cycles are available only with the Touch
probe function software option (option number #17).
