20.6 Measuring tool length and radius (Cycle
33 or 483, DIN/ISO: G483)

Cycle run

To measure both the length and radius of a tool, program
the measuring cycle TCH PROBE 33 or TCH PROBE 483
(See "Differences between Cycles 31 to 33 and Cycles 481 to
483", page 719). 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 31 and 32 as well as .

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.
The functioning of the cycle is dependent on machine
parameter probingCapability (No. 122723). (This
parameter permits e.g. tool length measurement with
a stationary spindle to be enabled and tool radius- and
individual tooth measurement to be simultaneously
disabled.) Refer to your machine manual.
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 CfgTT (No. 122700) Refer to your
machine manual.
