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 467). 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.
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.
