The invention concerns a method of machining a workpiece, wherein an end-facing tooth edge of a gear profile of the workpiece that was generated by a chip-removing machining process is reworked at a first location into a chamfered edge by way of a plastic forming operation. The material which in the plastic forming operation was displaced towards the end surface of the gear profile is pushed outward as a material protrusion in the end surface of the tooth, while the material displaced towards the flank of the tooth is pushed outward as a material protrusion on the flank side of the chamfer, and the resulting material protrusions in the end surface and on the flank side are removed. The workpiece, while still carrying the material protrusion on the end surface of the gear profile, is transferred to a second location where the protrusion on the flank side of the chamfer is removed.
A method of machining a first workpiece (A, B, C, D, E, F) having two end surfaces that are interconnected by a peripheral face, the peripheral face comprising a gear profile of a plurality of teeth, each tooth having tooth flank sides, the gear profile having been formed on the first workpiece by a chip-removing machining process, wherein the edge of one of the tooth flank sides at one of the end surfaces of the gear profile is changed by way of a plastic forming operation at a first location (β) into a chamfered edge, wherein material displaced in the plastic forming operation towards the end face of the gear profile gives rise to an end-facing material protrusion on the one end surface, while material displaced towards the one tooth flank side of the gear profile causes a material protrusion on the one flank side, and wherein the resulting material protrusions on the one end surface and on the one flank side are removed by said method,
