  • Publication number: 20230264281
    Abstract: The invention relates to a method for machining toothing systems, in which, for a series of workpieces with an identical target geometry, a toothing system is produced or machined on a respective workpiece in a first machining operation and, in a second machining operation, with a machining tool, additional tooth shaping of the toothing system resulting from the first machining - in particular, chamfering of a tooth end edge of this toothing system - is carried out in a relative positioning with respect thereto, wherein a controller of the second machining operation automatically detects, at least in part, a change in a workpiece property, which is in particular independent of the first machining operation, and/or in a setting of the first machining operation - in particular, with respect to a respectively predetermined reference - and carries out the relative positioning as a function of the detected change.

  • Patent number: 11179788
    Abstract: The invention relates to a method for producing a removal of material on a tooth end edge of a workpiece toothing with a rotationally driven chamfering tool in a machining operation brought about by controlled axial machine movements between the chamfering tool and the likewise rotationally driven workpiece toothing, wherein material is removed with a geometrically undefined cutting edge and the removal takes place in a coordinated action between a profiling, in particular, an alterable profiling, of the chamfering tool and a machine control used for the machining operation, performed in dependence on predetermined parameters that are characteristic of the removal of material to be produced.

  • Publication number: 20200391313
    Abstract: The invention relates to a chamfering tool (4) for chamfering workpiece toothings (22), comprising a helical toothing having, for each flight, a plurality of teeth (5) with a geometrically defined cutting edge and having a tooth profile (8, 9; 8?, 9?) which is designed for single-flank machining in rolling machining engagement with the workpiece toothing and asymmetrical as viewed in the axial section of the tool. The invention further relates to a chamfering system (100), to a gear-cutting machine, and to a method for producing a chamfer on the tooth edges of a tooth flank side of a workpiece toothing.

  • Patent number: 10675696
    Abstract: The invention relates to a method for machining a toothing that is chamfered on a tooth head front edge, in which a material projection resulting on said tooth head front edge chamfer, caused by chamfer formation on a tooth front edge of the toothing by means of plastic deformation, and/or caused by removing a primary/secondary burr produced on said end face during production of the toothing and, if applicable, formation of the tooth front edge chamfer, is removed in a rotational operation by a machining procedure with a machining tool that has a cutting edge.

  • Patent number: 10239139
    Abstract: The invention relates to a method for machining a toothing, wherein to form a chamfer on a tooth edge formed between an end face of the toothing and a tooth flank belonging to a tooth space of the toothing, material is removed from the tooth edge by cutting, by means of a machining tool equipped with a cutting edge, in a machining operation, wherein the machining tool is toothed and the machining operation is a skiving machining operation at an axis intersection angle between the rotational axes of the machining tool and the toothing, which does not extend beyond the tooth root section of the tooth space.
