Abstract

See full text

A method for precision machining a workpiece with gearing, wherein teeth of a gear-cutting tool rotating about a rotation axis are brought into engagement with teeth of the workpiece rotating about a workpiece rotation axis, and the gear-cutting tool and the workpiece are moved relative to each other in an axial direction parallel to the workpiece rotation axis. The thickness of the teeth of the gear-cutting tool, starting from an end face, increases in the axial direction until a thickness maximum is reached. The ratio (Bw/Bz) of the width (Bw) of the teeth of the workpiece to the width (Bz) of the teeth of the gear-cutting tool is 2-20. Before and after each pass of the teeth of the gear-cutting tool through the tooth gaps of the workpiece, the thickness maximum of each tooth of the gear-cutting tool is positioned outside the gearing of the workpiece.
