6.4.3 Nonlinear Axis Error Compensation
December 2001
Errors in machine geometry (e.g. an error in one axis caused by the sagging of
another axis) or external influences (e.g. temperature) can cause nonlinear axis
errors. These graphics show typical nonlinear axis errors:
The best way to measure nonlinear axis error is with a comparator measuring
system such as the HEIDENHAIN VM 101.
Note
The TNC can compensate screw-pitch error and axis sag simultaneously.
