Measuring the tool radius (touch probe cycle 32
or 482, ISO: G482)
To measure the tool radius, program the cycle TCH PROBE 32 or
TCH PROBE 482 (see also “Differences between Cycles 31 to 33 and
Cycles 481 to 483” on page 178). Depending on the input parameters,
you can measure the radius of a tool by:
„ Measuring the tool while it is rotating.
„ Measuring the tool while it is rotating and subsequently measuring
the individual teeth.
Sequence of measurement
The TNC pre-positions the tool to be measured to a position at the side
of the touch probe head. The distance from the tip of the milling tool
to the upper edge of the touch probe head is defined in MP6530. The
TNC probes the tool radially while it is rotating. If you have
programmed a subsequent measurement of individual teeth, the TNC
measures the radius of each tooth with the aid of oriented spindle
stops.
Before measuring a tool for the first time, enter the
following data on the tool into the tool table TOOL.T: the
approximate radius, the approximate length, the number
of teeth, and the cutting direction.
Cylindrical tools with diamond surfaces can be measured
with stationary spindle. To do so, define the number of
teeth (CUT) with 0 and adjust the machine parameter
6500. Refer to your machine manual.
