Abstract
The invention relates to a method for controlling movement of at least one subassembly of a machine tool, wherein the subassembly includes a rotatable spindle supported at the subassembly by at least one magnetic bearing having at least one bearing gap, wherein the subassembly is moved along a path smoothed by a controller with respect to an exact path, wherein the spindle in its housing is moved along a differential path by means of the magnetic bearing, and wherein the addition (superimposition) of the smoothed path and the differential path generated therewith results in the exact path.

A method for controlling movement of at least one machine tool subassembly comprising a rotatable spindle supported at the subassembly by at least one magnetic bearing including at least one bearing gap, the method comprising:
- moving the subassembly along a path smoothed by a controller with respect to an exact path;
- and
- moving the spindle in a housing along a differential path by a magnetic bearing,
- wherein superimposition of the smoothed path and the differential path generated therewith results in the exact path.
