Measure the drift of the axes at regular intervals.
Insert the touch probe
Activate the preset in the calibration sphere.
Use Cycle 452 to measure the kinematics.
The preset and the position of the calibration sphere must not be
changed during the complete process
This procedure can also be performed on machines
without rotary axes.
