288 Touch Probe Cycles: Automatic Measurement of Workpiece Misalignment

undamentals
14.1 Fundamentals
Overview
The TNC provides five cycles that enable you to measure and
compensate workpiece misalignment. In addition, you can reset a
basic rotation with Cycle 404:
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.
