18.4 Measuring the Tool Radius
(Cycle 32 or 482, ISO: G482)
Cycle run
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 419). Via input parameters you can
measure the radius of a tool by two methods:
„ Measuring the tool while it is rotating.
„ Measuring the tool while it is rotating and subsequently measuring
the individual teeth.
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
offsetToolAxis. The TNC probes the tool radially while it is rotating. If
you have programmed a subsequent measurement of individual teeth,
the control measures the radius of each tooth with the aid of oriented
spindle stops.
Please note while programming:
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 in the tool table and adjust the machine
parameter CfgToolMeasurement. Refer to your machine
tool manual.
