Abstract

A method for finish-machining a workpiece surface includes moving the workpiece surface relative to an active area of the finishing tool in a rotation direction about a workpiece axis, and superimposing on the relative movement of the workpiece surface and the active area an additional oscillatory movement with an oscillation frequency lower than 20 kHz in a direction perpendicular to the workpiece surface.
