490 Touch Probe Cycles: Automatic Kinematics Measurement
18.5 PRESET COMPENSATION (Cycle 452, DIN/ISO: G452, Option)
U Measure the drift of the axes at regular intervals.
U Insert the touch probe.
U Activate the preset in the calibration sphere.
U Use Cycle 452 to measure the kinematics.
U The preset and the position of the calibration sphere must not be
changed during the complete process.
Example: Drift compensation
