Calibration, calibration tool
A probe must be calibrated before it can be used. To do this, when using measuring cycles in
the AUTOMATIC mode, before calibration, the approximate values must be entered into the
setting data listed above for the corresponding probe. Only then can the approximate position
of the probe be identified in the measuring cycle.
Calibration involves precisely determining the trigger points (switching points) of the tool probe,
and entering them in the corresponding parameters.
Calibration tool (type 725), milling (type 1xy) or drilling tool (2xy) can be used for calibration.
The precise dimensions of the tool are known.
Measurement version Calibrate probe (CYCLE971) (Page 281) is provided for calibration.
Note
Measuring velocities
It is recommended that the same measuring velocities are used for calibrating and measuring.
