<p>A method of correcting positional fluctuations of a machine, particularly correcting the positional fluctuations of a machine tool having at least two control axes. A position-correcting means (12) outputs correction pulses (Xcp, Ycp) in such a manner that the ratio between the values in error registers (3X, 3Y) of the respective axes coincides with the ratio (R1) between the values of distribution pulses (Xp1, Yp1) of the respective axes. These correction pulses (Xcp, Ycp) are added to the distribution pulses (Xp1, Yp1), so that abruptly increased errors in a finished shape occurring during the finishing of the corners of a work which is performed at the start and immediately before the end of finishing can be minimized.</p> |
