Abstract
A method for production of a workpiece having a corrected gear tooth geometry and/or a modified surface structure by a diagonal generating method with a modified tool, wherein a modification in the generating pattern has a constant value in a first direction of the tool and is given by a function Fin a second direction of the tool, which extends perpendicular to the first direction, and/or wherein the modification is produced in that the position of the dresser to the tool is varied during dressing in dependence on the angle of rotation of the tool and/or on the tool width position, wherein the modification of the tool produces a corresponding modification on the surface of the workpiece, and wherein the modification of the workpiece produced by the modification is superposed by a profile modification and/or a modification caused by a change of the machine kinematics during the machining process.
