Calibrating the tool probe

To be able to measure your tools automatically, you must first determine the position of the
tool probe in the machine area in relation to the machine zero.
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.
Sequence of operations
You must approach the probe from four directions (+X, -X, +Z, -Z) for calibration purposes.
To do this, use a calibrating tool that you can use to approach the tool probe in all the
required directions.
The calibrating tool must be a turning tool type (roughing or finishing tool). Cutting edge
positions 1 - 4 can be used for the tool probe calibration. You must enter the length and the
radius or diameter of the calibrating tool in the tool list.

6. Press the "CYCLE START" key.
The automatic measuring process is started, i.e. the tool is traversed
at the measurement feedrate to the probe and back again.
The tool length is calculated and entered in the tool list. Whereby the
cutting edge position and tool radius or diameter are automatically
taken into consideration as well.
1. Change the calibrating tool.
2. Select "JOG" mode in the "Machine" operating area.
