Install the tool probe in theworking area of the machine (e.g on the machine table) and align it relative to the machiningaxes.You must use a mill-type calibration tool to calibrate the tool probe. You must enter thelength and radius/diameter of the calibration tool in the tool list beforehand.NoteSetting the protection levelThe "Calibrate probe" function is only available if an adequate level of protection is set.Please refer to the machine manufacturer's specifications.Procedure1. Move the calibration tool until it is approximately over the center of themeasuring surface of the tool probe.2. Select operating mode "JOG" in the "Machine" operating area andpress the "Measure tool" softkey.3. Press the "Probe calibration” softkey.4. Choose whether you want to calibrate the length or the length and thediameter.5. Press the key.Calibration is automatically executed at the measuring feedrate. Thedistance measurements between the machine zero and tool probe arecalculated and stored in an internal data area.
