Method for manufacturing a gear on a workpiece, using two-part finishing.

Abstract

A method for producing a gear (6) on a workpiece (1) by combined gear hobbing and chamfering, comprising the following steps: Step A): Roughing (Rh A) of the gear (6); Step B): Chamfering (C B) of at least part of the end faces (ST) of the gear (6); Step C): Finishing (Fh C) of the gear (6); is characterized in that in step C) during finishing (C) a first partial machining operation takes place in a first partial machining operation in which a first partial machining operation in which a first partial machining operation in which a second partial machining operation in which a second partial machining operation in which a second partial machining operation in which a second partial machining operation in which a second partial machining operation in which a second axial end (E2) of the toothing in which a second axial end (E2) is taken is carried out, and that the first partial machining operation is carried out with a first cutting direction (S1) of a milling tool (2), so that at the first axial end (E1) material is cut from axially outside to axially inside,and the second partial machining operation is carried out with a second cutting direction (S2) of a milling tool (2), which is opposite to the first cutting direction (S1), so that material is also cut from axially outside to axially inside at the second axial end (E2). With the invention, a gear can be manufactured in a workpiece with a high surface finish in a simple manner, whereby burrs on the finished workpiece can be avoided.
