2.7.4 Calibrating a measuring probe
If you want to measure your tools automatically, you must first
determine the position of the probe on the machine table with
reference to the machine zero.
Mechanical tool measuring probes are typically shaped like a cube or
a cylindrical disk. Install the probe in the working area of the machine
(on the machine table) and align it relative to the machining axes.
You must use a mill-type calibration tool to calibrate the measuring
probe. You must enter the length and radius/diameter of the tool in the
tool list beforehand.
îš¾ Move the calibration tool until it is approximately over the center o
the measuring surface of the probe.

îš¾ Press the "Cycle Start" key.
Calibration is automatically executed at the measuring feedrate.
The distance measurements between the machine zero and
measuring probe are calculated and stored in an internal data area.
