DIN/ISO: G482, Option 17)

Cycle run

To measure the tool radius, program the measuring cycle TCH
PROBE 32 or TCH PROBE 482 (see "Differences between Cycles
31 to 33 and Cycles 481 to 483", Page 523). Select via input
parameters by which of two methods the radius of a tool is to be
measured:
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.
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.
