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.
Refer to your machine manual.
The TNC provides five cycles that enable you to measure and
compensate workpiece misalignment. In addition, you can reset a
