20.9 Measuring the tool length and
radius (Cycle 483)
Cycle run
To measure the tool length and radius, program Cycle TCH PROBE
483. This cycle is particularly suitable for the first measurement of
tools, as it saves time when compared with individual measurement
of length and radius. Via input parameters you can select the desired
type of measurement:
 Measuring the tool while it is rotating
 Measuring the tool while it is rotating and subsequently measuring
the individual teeth.
The TNC measures the tool in a fixed programmed sequence. First it
measures the tool radius, then the tool length. The sequence of
measurement is the same as for Cycles 481 and 482.
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 in the tool table
the number of teeth CUT as 0 and adjust machine
parameter CfgToolMeasurement. Refer to your machine
manual.
