Abstract
A method for producing a toothed workpiece gear, wherein the workpiece gear is clamped or fastened to a workpiece spindle, and a cutting tool having cutting teeth is clamped or fastened to a tool spindle. The tool spindle and the workpiece spindle are rotationally driven at a coupling ratio of the angles of rotation thereof having a periodic non-linearity or an axial distance from each other that changes periodically. The cutting teeth machine forms left and right tooth flanks of the teeth of the workpiece gear using left and right cutting edges in a chip-removing manner. A radial run-out error or a pitch error of the cutting tool is determined. The flank line shape errors of the right and left tooth flank resulting from the radial run-out error or the pitch error are reduced by the periodic non-linearity of the coupling ratio or the periodic change in the axial distance.
