The invention relates to a method for toothing machining, in which, on a toothing machine controlled by a control device, a toothing is produced or machined, on a workpiece clamped on a workpiece spindle arranged at a first machine position, by a toothing tool driven rotationally on a first tool spindle, and, subsequently, in the same workpiece clamping operation or in a clamping operation of the machined toothed workpiece on a workpiece spindle arranged at a second machine position, with synchronized rotation of the workpiece and a workpiece-specific chamfering tool driven rotationally by a second tool spindle, and with a feed movement between the chamfering tool and the workpiece, a chamfer is produced by cutting with a cutting edge of the chamfering tool on a tooth end edge of a tooth flank of the workpiece toothing, wherein, during chamfering, the axial distance between the axes of rotation of the workpiece and the chamfering tool is not greater than half a pitch of the workpiece toothing, the axis crossing angle between the tool axis of rotation and the workpiece axis of rotation and/or the axis crossing angle between the tool axis of rotation and a surface normal to the end face of the workpiece adjacent to the machined tooth end edge differs from 90° by not more than 12°, preferably not more than 8°, in particular not more than 4°, the predominant directional component of the feed movement runs in the direction of the tool axis of rotation, and the cutting edge has a greater directional component in the direction of the axis of rotation of the chamfering tool than in the plane of rotation orthogonal thereto, at least in its portion chamfering in the region at half the tooth height of the workpiece toothing.
A method for toothing machining, in which, on a toothing machine (500) controlled by a control device, a toothing is produced or machined, on a workpiece clamped on a workpiece spindle arranged at a first machine position, by a toothing tool driven rotationally on a first tool spindle, and, subsequently, in the same workpiece clamping operation or in a clamping operation of the machined toothed workpiece on a workpiece spindle (10) arranged at a second machine position, with synchronized rotation of the workpiece and a workpiece-specific chamfering tool (1) for the workpiece driven rotationally by a second tool spindle, and with a feed movement (V) between the chamfering tool and the workpiece, a chamfer is produced by cutting with a cutting edge (15) of the chamfering tool on a tooth end edge (5) of a tooth flank of the workpiece toothing, wherein, during chamfering, the axial distance between the axes of rotation of the workpiece and the chamfering tool is not greater than half a pitch of the workpiece toothing, the axis crossing angle between the tool axis of rotation and the workpiece axis of rotation and/or the axis crossing angle between the tool axis of rotation and a surface normal to the end face (6) of the workpiece adjacent to the machined tooth end edge differs from 90° by not more than 12°, the predominant directional component of the feed movement (V) runs in the direction of the tool axis of rotation, and the cutting edge has a greater directional component in the direction of the axis of rotation of the chamfering tool than in the plane of rotation orthogonal thereto, at least in its portion chamfering in the region at half the tooth height of the workpiece toothing.
An arrangement for toothing machining, with which, on a toothing machine controlled by a control device, a toothing is produced or machined, on a workpiece clamped on a workpiece spindle arranged at a first machine position, by a toothing tool driven rotationally on a first tool spindle, and, subsequently, in the same workpiece clamping operation or in a clamping operation of the machined toothed workpiece on a workpiece spindle arranged at a second machine position, with synchronized rotation of the workpiece and a workpiece-specific chamfering tool driven rotationally by a second tool spindle, and with a feed movement between the chamfering tool and the workpiece, a chamfer is produced by cutting with a cutting edge of the chamfering tool on a tooth end edge of a tooth flank of the workpiece toothing, wherein, during chamfering, an axial distance between the axes of rotation of the workpiece and the chamfering tool is not greater than half a pitch of the workpiece toothing, the axis crossing angle between the tool axis of rotation and the workpiece axis of rotation and/or the axis crossing angle between the tool axis of rotation and a surface normal to the end face of the workpiece adjacent to the machined tooth end edge differs from 90° by not more than 12°, the predominant directional component of the feed movement runs in the direction of the tool axis of rotation, and in particular the cutting edge has a greater directional component in the direction of the axis of rotation of the chamfering tool than in the plane of rotation orthogonal thereto, at least in its portion chamfering in the region at half the tooth height of the workpiece toothing.
