A method for the manufacture of a gear component includes, in a soft machining process, introducing a preliminary toothing 3 with a machining allowance 7 that is fixed relative to a final toothing 4 into a blank such that a semi-finished part 2 is produced. The method also includes, in a fine machining process, removing the machining allowance 7 and producing the final toothing 4 of the toothed component. The machining allowance 7 is removed in a single-stage hobbing method by a grinding tool 1, wherein the grinding tool 1 removes the machining allowance completely in a single stroke movement H.

Method for cutting a gear (4) from a metal workpiece (2), in which a tooth flank, still having an oversize compared with its predefined final geometry, of the gear is, in one or more cutting passes in cutting engagement with one or more cutting tools (10) fed thereto, hard-fine finished with a geometrically undefined cutting edge made of cutting grains incorporated in a binder matrix, in order to produce a reflective property, existing in the final geometry, of its surface, wherein, in a cutting pass of a cutting tool (10b), both an elastically resilient mounting of the cutting grains set by its binder matrix acts on this surface property, and a cutting reduction of the oversize by at least 2 μm at the tooth flank is realized by a compressive preload, set via the infeed of the cutting tool, to which the cutting engagement is subjected; as well as a gear-cutting tool and a machine tool for this purpose.

A method for grinding a toothing of a workpiece with a grinding tool in a grinding machine, wherein during the engagement of the grinding tool in the toothing to be ground, a first and a second machine parameter are measured, and both machine parameters measured are compared with a predefined stored value, wherein a signal is output if at least one of the machine parameters exceeds or falls below the predefined stored value, taking account of a tolerance range. To enable a conclusion to be drawn about the course of the grinding process by monitoring relevant variables, at least one of the machine parameters contains periodic signal components, wherein the signal components are broken down by a frequency analysis into the individual frequency components and the frequency components are used, with regard to their frequency and/or amplitude, for comparison.

A method for continuous generating grinding of at least two gear workpieces with a topologically modified grinding worm comprising a topologically modified worm region to grind tooth flanks which are topologically modified on the gear workpieces, wherein the method comprises at least the following steps: a) providing a first gear workpiece, b) performing a topological generating grinding operation by carrying out relative movements between the first gear workpiece and the grinding worm, which comprises a relative feed movement, a relative axial feed which occurs parallel or obliquely to the tool rotation axis, and a relative shift movement, c) providing the second gear workpiece, d) performing a relative jumping motion extending substantially parallel or obliquely to the tool rotation axis between the second gear workpiece and the grinding worm, e) repeating step b) for the second gear workpiece.

A method for hard fine machining of the toothing of a gear that has an axis of rotation, wherein the toothing is machined with a hard fine machining tool. The machining tool rotates around an axis of rotation during hard fine machining. The method includes: a) Providing a hard fine machining tool that has axially adjacent machining zones, including a first zone for the grinding the toothing and a second zone for fine grinding and/or polishing the toothing; b) Grinding the toothing with the first zone, wherein a first pivoting angle exists between the axis of rotation of the gear and the axis of rotation of the machining tool; c) Fine grinding and/or polishing the toothing with the second zone of the machining tool, wherein a second pivoting angle exists, which is different from the first pivoting angle, between the axis of rotation of the gear and the axis of rotation of the machining tool.

A method for grinding a gear toothing, in which a target value with a tolerance range is defined for the tooth width. The method includes: a) measuring the location of the surface of the tooth flanks of the gear at at least two axial positions offset in the direction of the axis of rotation; b) determining the actually present allowance of the gear based on the measured values determined in step a); c) grinding the toothing by radial infeed of the grinding tool relative to the toothing, c1) wherein the radial infeed corresponds to the target value of the tooth width, if the determination under step b) indicated that such an allowance is present on all tooth flanks that material will be removed from all tooth flanks, or c2) wherein the radial infeed takes place at a value higher than the target value of the tooth width, the higher value still corresponding to the tolerance range for the tooth width, if the determination under step b) indicated that such an allowance is present on all tooth flanks that material will be removed from all tooth flanks only with increased radial infeed.

A hub flange has a fixed flange configured to receive a tool body. A flange socket is formed on the fixed flange for connection to a spindle shaft. A counterflange is detachably connected to the fixed flange. The fixed flange and the counterflange are connected to each other via a conical connection, wherein the conical connection is arranged coaxially to the tool axis and is formed by an inner cone and an outer cone received therein.

A method for grinding the toothing or the profile of a workpiece that has an axis of rotation and wherein an allowance is ground away from the surface of the tooth flanks of the toothing or the profile. The method includes the following steps: a) measuring the position of the surface of the tooth flanks of the toothing or the profile, wherein the measuring is carried out in at least two positions of the workpiece, which are arranged offset in the direction of the axis of rotation; b) determining the actually existing allowance of the workpiece that has not yet been ground, based on the measurement values from step a); c) determining at least one grinding parameter so that the material removal per time has a predetermined value or does not exceed a predefined value during grinding; and d) grinding the workpiece with the grinding parameters established in step c).

Method for the grinding of a gear wheel workpiece using a dressable worm grinding wheel, wherein the worm grinding wheel is rotationally driven about a tool axis of rotation and the gear wheel workpiece is rotationally driven about a workpiece axis of rotation, and relative movements are executed between the worm grinding wheel and gear wheel workpiece, and wherein after the execution of a dressing procedure of the worm grinding wheel, which is carried out by means of a rotationally-drivable dressing unit, the following steps are carried out: executing a relative shift movement between the worm grinding wheel and gear wheel workpiece parallel to the tool axis of rotation, executing an axially-parallel relative movement between the worm grinding wheel and gear wheel workpiece in parallel or diagonally to the workpiece axis of rotation,
wherein a ratio between the shift movement and axially-parallel relative movement is specified, which is variable.
