Abstract: The present study develops a new compensation method, the decouple method, for geometry errors of five-axis machine tools. The method proposed is based on a model that the tool orientation error only related to motion of machine rotation axes, a Abstract: The present study develops a new compensation method, the decouple method, for geometry errors of five-axis machine tools.
