Calibrating the electrical tool probe

If you want to measure your tools automatically, you must first determine the position of the
tool probe on the machine table with reference to the machine zero.
Tool probes are typically shaped like a cube or a cylindrical disk. Install the tool probe in the
working area of the machine (e.g on the machine table) and align it relative to the machining
axes.
You must use a mill-type calibration tool to calibrate the tool probe. You must enter the
length and radius/diameter of the calibration tool in the tool list beforehand.
Note
Setting the protection level
The "Calibrate probe" function is only available if an adequate level of protection is set.
Please refer to the machine manufacturer's specifications.

6. If necessary, enter the lateral offset V.
7. Press the <CYCLE START> key.
This starts the automatic measuring process. When you measure the
tool radius or diameter, measurement is performed with a spindle
rotating in the opposite direction.
The tool length, radius, and diameter are calculated automatically and
entered in the tool list.
1. Move the calibration tool until it is approximately over the center of the
measuring surface of the tool probe.
2. Select operating mode "JOG" in the "Machine" operating area and
press the "Measure tool" softkey.
3. Press the "Probe calibration" softkey.
