DIN/ISO: G451, option)
Cycle run
The touch probe cycle 451 enables you to check and, if required,
optimize the kinematics of your machine. Use the 3-D TS touch
probe to measure a HEIDENHAIN calibration sphere that you have
attached to the machine table.
HEIDENHAIN recommends using the calibration
spheres
KKH 250 (ID number 655 475-01) or KKH
100 (ID number 655 475-02) , which have particularly
high rigidity and are designed especially for machine
calibration. Please contact HEIDENHAIN if you have
any questions in this regard.
The TNC evaluates the static tilting accuracy. The software
minimizes the spatial error arising from the tilting movements and,
at the end of the measurement process, automatically saves the
machine geometry in the respective machine constants of the
kinematics description.
1 Clamp the calibration sphere and check for potential collisions.
2 In the Manual Operation mode, set the reference point in
the center of the sphere or, if Q431=1 or Q431=3 is defined:
Manually position the touch probe over the calibration sphere
in the touch probe axis, and in the center of the sphere in the
working plane.
3 Select the Program Run mode and start the calibration program.
4 The TNC automatically measures all three axes successively in
the resolution you defined.
5 The TNC saves the measured values in the following Q
parameters:
