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 ball that you have attached to
the machine table.
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 ball and check for potential collisions
2 In the Manual Operation mode, set the reference point in the ball
center, or if Q431=1 or Q431=3 is defined: In the touch probe axis,
manually position the touch probe over the calibration ball, and in
the working plane, over the ball center.
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.
HEIDENHAIN recommends using the HEIDENHAIN
calibration balls KKH 250 (ID number 655 475-01) or KKH
100 (ID number 655 475-02) , which have high rigidity and
are designed especially for machine calibration. Please
contact HEIDENHAIN if you have any questions in this
regard.
