16.1 Fundamentals
Overview
When running touch probe cycles, Cycle 8 MIRROR
IMAGE, Cycle 11 SCALING and Cycle 26 AXIS-SPECIFIC
SCALING must not be active.
HEIDENHAIN only gives warranty for the function of the
probing cycles if HEIDENHAIN touch probes are used.
The TNC must be specially prepared by the machine tool
builder for the use of a 3-D touch probe.
The TNC offers twelve cycles for measuring workpieces
automatically.
