756 HEIDENHAIN Technical Manual iTNC 530 HSCI
Example of AC table:
After the A axis has been measured, its angular position is determined and
optimized. Adjustments are only possible through compensations in the
COMPTAB column if a numerical value is entered in the corresponding lines. This
is the case in lines 8 and 9 of this example, where the position errors B0A and
C0A can be defined. After the A axis has been defined, Cycle 451 tries to
cancel the rotations, which have just been performed. This is done by the
compensations defined in lines 11 and 12 immediately afterwards. The two
rotations are arranged inversely to the way they are arranged in lines 8 and 9.
This simplifies traceability, but it is not absolutely necessary. After the angular
position has been adjusted, a measurement is performed, in which the
position of the rotary axis (Y0A and Z0A) is determined. The position is
corrected in lines 6 and 7.
