1.7 Probe, calibration body, calibration tool
Calibration, gauging block
A probe must be calibrated before it can be used. Calibration involves precisely determining
the triggering points (switching points) of the tool probe and entering them in special data
fields.
Calibration is performed with a calibration tool. The precise dimensions of the tool are
known.
Use the same measuring velocity for calibrating and measuring.
A special measuring variant in a cycle is available for calibration.
On turning machines, the calibration tool is treated like a turning tool with cutting edge
position 3. The lengths refer to the ball circumference, not to the ball center.
