  • Patent number: 10226830
    Abstract: A method for skiving machining a toothed workpiece includes the steps of: providing the toothed workpiece rotatable about a workpiece axis; providing a toothed tool rotatable about a tool axis; tilting the tool axis through an azimuth angle ?>0° with respect to an x direction; tilting the tool axis furthermore through a polar angle ?<90 ° with respect to a z direction; rotating the toothed tool about the tool axis, the toothed tool in a contact zone sliding over the toothed workpiece rotating about the workpiece axis. The workpiece axis defines the x direction and the perpendicular of the contact zone to the workpiece axis defines a z direction. The x direction, a y direction and the z direction form a Cartesian coordinate system. This method can easily produce a chamber on the toothed workpiece with the toothed tool which is subject to fewer geometric restrictions.

  • Publication number: 20160193648
    Abstract: A method for processing a toothed workpiece includes clamping it on a rotating workpiece spindle and engaging it with a first and second tool set. The first tool set engages at the first side of the workpiece with a wedge-like tool portion laterally in the tooth gaps on the workpiece, wherein the tooth front edges are chamfered on front tooth flanks with respect to a running direction of the workpiece and a smoothing of the tooth flanks is carried out close to the tooth front edges on rear tooth flanks with respect to the running direction. The second tool set engages the first side, but the tooth front edges are now smoothed on front tooth flanks and a chamfering of the tooth flanks close to the tooth front edges on rear tooth flanks is carried out. Larger chamfer angles can now readily be produced on tooth edges of the workpiece.
