Claim Text:
1. A method for positioning machine axes of a machine tool, comprising: converting, by a numerical control device, setpoint positions of a tool, predefined in workpiece coordinates, into setpoint positions of machine axes based on a kinematic chain defined by a kinematic table, each of the machine axes having a respective axial direction, transformations of the coordinates being provided in the kinematic table in a plurality of entries describing the kinematics of the machine tool; wherein the kinematic table includes at least one first entry that specifies one respective axial direction and one associated transformation amount; and wherein the kinematic table includes at least one second entry that specifies an error transformation amount in a first respective axial direction as a function of an axial position of the machine tool in a second respective axial direction, the first respective axial direction being different from the second respective axial direction.
