METHOD OF MACHINING A WORKPIECE, AND GEAR-CUTTING MACHINE OPERABLE TO PERFORM THE METHOD

摘要

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.

主权项

1. A method of machining a workpiece (A, B, C, D, E, F) wherein the edge at the end of a tooth flank of a gear profile which has been formed on the workpiece by a chip-removing machining process is changed by way of a plastic forming operation at a first location (β) into a chamfered edge, wherein the material displaced in the plastic forming operation towards the end face of the gear profile gives rise to an end-facing material protrusion, while the material displaced towards the tooth flank of the gear profile causes a material protrusion on the flank side, and wherein the resulting material protrusions in the end surface and on the flank side are removed by said method, characterized in that the workpiece, while still carrying the end-facing material protrusion, is switched to a second location (γ), where the removal of the material protrusion on the flank side takes place.
