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.
