Abstract
In a method for positioning machine axes in machine tools, a numerical control converts 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. In this context, transformations of the coordinates are indicated in the kinematic table in a plurality of entries describing the kinematics of the machine tool, by specifying an axial direction and an associated transformation amount, respectively, per entry. For a machine axis having an error in a direction other than the respective axial direction, error transformation amounts dependent on the axial position are entered into the kinematic table.
