摘要： The invention relates to a method for gear shaping a periodic structure, in particular a toothing on a workpiece, in which method the workpiece, continuously rotating about its axis of rotation, is brought into material-removing machining engagement with a toothed shaping tool which rotates about its axis of rotation in rolling contact with the workpiece rotation. After a working stroke, the shaping tool is lifted off from the workpiece in a lifting direction and, after a subsequent return stroke, the shaping tool in the lifted state is returned to the workpiece again for the next working stroke. In the return stroke, a deflection movement of the shaping tool away from the incoming flank of the workpiece and transversely to the lifting direction is superimposed on the rolling contact.

摘要： The invention relates to a method for machining a toothing (2) having an axis of rotation (C), in which a machining tool (4), which is rotationally driven about its axis of rotation (B), removes material from the toothing while executing a relative motion between the machining tool and toothing to generate a flank geometry of the toothing, which has been predefined over the full width of the toothing, in a machining operation, wherein the predefined flank geometry matches a motion control that defines a motion path of the tool center with respect to the toothing axis of rotation, said motion control having a defined, non-vanishing axial advancement with a defined advancing motion between machining tool and toothing, wherein in a first machining process, the relative motion is only executed for generating a part, more particularly a significant part (5), of the flank geometry according to this motion control, while a further part, more particularly the remaining part (6), of the flank geometry is generated in a second machining process, in which the distance between the tool center and the toothing axis of rotation with respect to the fixed motion path changes in a manner wherein the tool center moves away from the toothing, and in which the change to the machining operation caused thereby is counteracted by an additionally executed change in motion of the relative motion with respect to the motion control of the first machining process.

摘要： The invention concerns a method to generate and/or machine gear teeth on a workpiece, wherein the workpiece is subjected to a movement from a first location where the workpiece, while being held by a clamping device connected to a workpiece spindle, is brought into machining engagement with a first tool, to a second location where the work piece, while remaining in its clamped condition, is brought into machining engagement with a second tool, wherein prior to performing the movement, the connection between the clamping device and the workpiece spindle is released, and after the movement, the clamping device is connected to another workpiece spindle for the machining engagement with the second tool.

摘要： The invention concerns a method for the machining of the tooth edges between an axially facing surface and the tooth flanks of a gear with a machining tool that has a toothed contour. For the material-removing cutting operation, the machining tool, rotating about the axis of its toothed contour, is brought into rolling engagement with the toothed workpiece under a crossing angle different from zero between the rotary axes of the machining tool and the toothed workpiece.

摘要： The invention concerns a method for the chip-removing generation or machining of internal gear teeth on a workpiece which is rotatable about its rotary axis and radially delimits a free space that extends axially to one side beyond the internally toothed region and whose radial width narrows in the direction of its axial extension in at least one location. An externally toothed tool which is driven in rotary movement about its axis of rotation is brought from the opposite side into rolling engagement with the internally toothed region with the rotary axes crossed at an angle. Through the application of a mechanical force, the chips which are produced in the process and which are subject to a centrifugal force are caused to change their movement in the zone of narrowing width in a manner directed against the origin of the centrifugal force.

摘要： In a method for the machining of a workpiece (2) which is driven in rotary movement about a workpiece axis (Z) and whose shape includes a periodic structure, specifically a workpiece with gear teeth, a cutting tool which has gear-like teeth with a cutting edge formed at a frontal end of the teeth and which is driven in rotary movement about a cutting tool axis that is radially spaced apart from the workpiece axis, is brought into a rolling engagement with the workpiece under a crossing angle between the two rotary axes, wherein the cutting edge removes material from the workpiece through a cutting movement that has a component in the direction parallel to the workpiece axis, and wherein for the machining of the workpiece over a desired axial range the cutting tool is in addition made to perform a feed movement having a component parallel to the workpiece axis. According to the method, the feed movement component parallel to the workpiece axis and the cutting movement component parallel to the workpiece axis are oriented in opposite directions relative to each other.

摘要： Tool head as seat and drive for the rotary motion of a tool to be bilaterally supported in the tool head. Near its ends, the tool has centering faces which fit into rotatably developed seat bushings in the tool head. One of said seat bushings is arranged in a drive carriage and the other in a counter-bearing, in alignment with each other. The counter-bearing is part of a counter-bearing carriage which can be displaced far enough on the drive carriages to seat the tool so that the tool, which is located between the carriages, is held with the centering faces in the bushings and a pre-adjusted axial force is present. A rotary drive motor is connected to the tool via a tool spindle supported in the drive carriage and a positive clutch. The tool is preferably developed as a shaft tool and is essentially symmetrical relative to a plane perpendicular to the axis of rotation in the center of a gear cutting enveloping body of the tool. The distance between the centering face and the gear cutting enveloping body on the drive side is as small as the required minimum corresponding distance on the side of the counter bearing.
