The present disclosure relates to a method of setting up a gear cutting machine, wherein the gear cutting machine is equipped with at least one machine part which can be set up and the parameters relating to the set-up machine part are input into the machine control for the subsequent gear cutting process, wherein a graphical model of the machine part is virtually composed on a display element of the gear cutting machine in a user-controlled manner from one or more graphical part components and the required parameters for the following gear cutting process are derived from the graphical modeling.

The present invention shows a process for gear manufacturing machining a workpiece by a tool on a gear manufacturing machine, wherein the workpiece is machined by a generating machining process in which the tool for gear manufacturing machining rolls off on the workpiece at a predefined center distance and axial cross angle, wherein the gear manufacturing machining preferably takes place on two flanks, with a desired tooth trace shape and/or tooth thickness of the gearing being generated by the generating machining process. The process is characterized in that an additional condition is predefinable and in that the center distance and the axial cross angle are determined in dependence on the desired tooth trace shape and/or tooth thickness of the gearing and on the additional condition.

A method of producing a workpiece having a modified gearing geometry by a generating method includes generating machining the workpiece in at least one machining stroke with a tool having a modified gearing geometry and a topological modification. Provision is made that the contact path with the workpiece is not shifted on the tool during the machining stroke. In one example, a cylindrical workpiece is machined by an axial generating method. In another example, a conical workpiece is machined by a diagonal generating method, and the diagonal ratio is selected such that the contact path does not shift on the tool during the machining stroke.

A profile gauge that embodies a measurement geometry for a tool that has a toothed profile designed in particular for the skiving of toothed work pieces, wherein the profile gauge serves to determine at least one measurement quantity which can be used for a machining process, specifically a skiving process, that is to be performed with the tool and wherein, in a phase of said process, the toothed profile of the work piece that is to be generated is formed by a meshing engagement with the teeth of the tool, wherein the profile gauge is distinguished by having a toothed profile section with which, for determining the measurement quantity, the teeth of the tool are brought into a meshing engagement that corresponds to the tooth engagement between the tool and the work piece during the profile-forming phase. The invention further concerns a measuring device and a measurement method.

A toothed workpiece having a modified surface geometry may be produced by a diagonal generating method by means of a modified tool whose surface geometry comprises a modification. The modification may be described by a linear and/or quadratic function, with the coefficients of this linear and/or quadratic function. Pitch and/or crowning of the modification may vary in dependence on the angle of rotation of the tool and/or on the tool width position. The specific modification of the tool produces a corresponding modification on the surface of the workpiece by the diagonal generating method, with a desired modification of the surface geometry of the workpiece being specified and a modification of the surface geometry of the tool suitable for producing this desired modification being determined in combination with a diagonal ratio of the diagonal generating method suitable for producing the desired modification.
