A geometric model fitting based calibration process determines offsets between the actual tool center point and theoretical tool center point of a numerically controlled machining system, thereby enabling the system to apply compensation to the offsets in order to align the actual and theoretical tool positions.

A calibration method for numerical controlled machine tools (1), 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 (1). The calibration method measures the positions of a calibration ball (6) with a measurement sequence which includes the combined movement of the calibration ball (6) 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).
