Abstract
A calibration method for numerical controlled machine tools (), which uses a kinematic model to generate a compensation model for the positioning error occurring with the movement of the linear (X, Y, Z) and rotation axes (B, C, A) of a machine tool (). The calibration method measures the positions of a calibration ball () with a measurement sequence which includes the combined movement of the calibration ball () around two rotation axes (C, B or C, A), wherein the measurements around a first rotation axis (C) include at least two rotational position movements around a second axis (B or A).
