Overview

Operating notes
When running touch probe cycles, Cycle 8 MIRROR
IMAGE, Cycle 11 SCALING and Cycle 26 AXIS-
SPECIFIC SCALING must not be active.
HEIDENHAIN only assumes liability for functionality
of the probing cycles if HEIDENHAIN touch probes
are used.
The TNC and the machine tool must be set up by the
machine tool builder for use of the TT touch probe.
Some cycles and functions may not be provided on your
machine tool. Refer to your machine manual.
The touch probe cycles are available only with the Touch
Probe Functions software option (option 17). If you
are using a HEIDENHAIN touch probe, this option is
available automatically.
In conjunction with the TNC's tool measurement cycles, the tool
touch probe enables you to measure tools automatically. The
compensation values for tool length and radius can be stored in
the central tool file TOOL.T and are accounted for at the end of the
touch probe cycle. The following types of tool measurement are
provided:
Tool measurement while the tool is at standstill
Tool measurement while the tool is rotating
Measurement of individual teeth
