Abstract
The present disclosure relates to a method for the manufacture of a workpiece having a corrected gear geometry and/or a modified surface structure, in particular by a hard finishing process, in particular generation grinding or honing. Provision is made in this respect that it is achieved by a direct generation of a wobble movement and/or of an eccentricity of the tool that a modification, in particular a profile modification or profile waviness, and/or a defined periodic flank waviness is generated on the active surface of the workpiece machined therewith.
Claims20
A method for the manufacture of a workpiece having a corrected gear geometry and/or a modified surface structure, wherein:
- it is achieved by a direct generation of a wobble movement and/or of an eccentricity of a tool that a modification is generated on the active surface of the workpiece machined therewith.
A method for the manufacture of a workpiece having a corrected gear geometry and/or a modified surface structure, wherein an engagement depth of a worm grinding wheel into the workpiece is varied, in the machining of the workpiece in dependence on an angle of rotation of the worm grinding wheel.
The gear cutting machine for dressing a worm grinding wheel having a dressing tool, including a gear cutting machine, wherein the gear cutting machine is configured for out-of-round dressing of a worm grinding wheel which sets a penetration depth of the dressing tool into the worm grinding wheel in dependence on an angle of rotation of the worm grinding wheel.
