A tool which can be used for gear manufacturing machining of a workpiece may be dressed on a dressing machine, and the dressing may take place with line contact between the dresser and the tool. A specific modification of the surface geometry of the tool is produced by the suitable selection of the position of the dresser with respect to the tool during dressing. The specific modification of the surface geometry of the workpiece is specifiable with regard to various parameters.

In a method of producing a toothed workpiece having a modified surface geometry by a diagonal generating method by means of a modified tool, a tool may be used whose surface geometry comprises a modification which can be described at least approximately in the generating pattern at least locally in a first direction of the tool by a linear and/or quadratic function, with the specific modification of the tool producing a corresponding modification on the surface of the workpiece by the diagonal generating method, with the modification of the workpiece produced by the specific modification of the tool having a profile modification and/or a modification caused by a change of the machine kinematics during the machining process of the workpiece superposed on it.

A toothed workpiece having a modified surface geometry may be produced by a diagonal machining method by means of a modified tool. The modification of the tool can be described at least approximately at least locally in the generating pattern in a first direction of the tool by a linear and/or quadratic function; the coefficients of this linear and/or quadratic function are formed in a second direction of the tool which extends perpendicular to the first direction. A pitch and/or crowning of the modification varies in dependence on the angle of rotation of the tool and/or on the tool width position, and a tooth thickness of the modified tool varies in a non-linear manner in dependence on the angle of rotation of the tool and/or on the tool width position.

A method of producing a tooth profile surface on a workpiece. The method comprises providing a gear cutting tool and rotating the gear cutting tool about an axis of rotation. The cutting tool and workpiece are engaged with one another and rolled together in accordance with a generating roll to generate a profile surface of a tooth. The generating roll comprises a first ratio-of roll and a second ratio-of-roll with the first and second ratios-of-roll being different from one another and with one of the first ratio-of-roll and the second ratio-of-roll resulting in a relief section being formed on the tooth profile surface.
