Option)
 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.
