undamentals
20.1 Fundamentals
Overview
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
You can program the cycles for tool measurement in the Programming
and Editing mode of operation via the TOUCH PROBE key. The
following cycles are available:
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 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 measuring cycles can be used only when the central
tool file TOOL.T is active.
Before working with the measuring cycles, you must first
enter all the required data into the central tool file and call
the tool to be measured with TOOL CALL.
