ISO: G451, option)

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

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 preset in the center

of the sphere or, if Q431=1 or

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

(ID number 655 475-01) or

475-02), which have particularly
