Touch Probe Cycles: Automatic Measurement of Workpiece Misalignment
15.1 F
undamentals
15.1 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:
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.
