Cycle run
Touch probe cycle 452 optimizes the kinematic transformation chain
of your machine (see "MEASURE KINEMATICS (Cycle 451, DIN/ISO:
G451; Option)" on page 480). Then the TNC corrects the workpiece
coordinate system in the kinematics model in such a way that the
current preset is in the center of the calibration sphere after
optimization.
This cycle enables you, for example, to adjust different
interchangeable heads so that the workpiece preset applies for all
heads.
1
Clamp the calibration sphere.
2 Measure the complete reference head with Cycle 451, and use
Cycle 451 to finally set the preset in the center of the sphere.
3 Insert the second head.
4 Use Cycle 452 to measure the interchangeable head up to the
point where the head is changed.
5 Use Cycle 452 to adjust other interchangeable heads to the
reference head.
