Abstract

A method reduces errors in a turning device during a determination of coordinates of a work piece or during machining of the work piece. The turning device allows a rotational movement of the work piece about a rotation axis of the turning device. The method includes measuring errors in the turning device on account of deviations between actual positions and actual orientations of the rotation axis, on the one hand, and corresponding ideal positions and ideal orientations of the rotation axis, on the other hand, in a range of rotation angles. Expected error values of the turning device are determined from error measurements and are used to correct the turning device.
