5.4 Measuring Tools with the TT 120
The TNC and the machine tool must be set up by the
machine tool builder for use of the TT 120 touch probe.
Some cycles and functions may not be provided on your
machine tool. Refer to your machine manual.
In conjunction with the TNC’s tool measurement cycles, the TT 120
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 in the next tool call. 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 define the tool measurement cycles in the
PROGRAMMING AND EDITING mode of operation. The following
cycles are available:
■ TCH PROBE 30.0 TT CALIBRATE
■ TCH PROBE 31.0 TOOL LENGTH
■ TCH PROBE 32.0 TOOL RADIUS
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.
Setting the machine parameters
The TNC uses the feed rate for probing defined in
MP6520 when measuring a tool at standstill.
When measuring a rotating tool, the TNC automatically calculates
the spindle speed and feed rate for probing.
