ABSTRACT:
A method for, via skiving, finishing the flanks of the teeth of a cylinder wheel that is provided with internal or external spur or helical gearing is generated. The right and left flanks of the teeth are provided in separate operations and, to produce helix modifications, the center distance, and/or the additional rotation, of the workpiece relative to the tool are altered over the face width of the gear. During axial movement, one or at the same time several of the setting parameters center distance, offset of the tool, swivel angle, and additional rotation are automatically altered in such a way that the distortion of the flanks that would be generated at conventional skiving of crowned gears is compensated for and a tool is used for the finishing that at the right and left flanks has a cutting edge geometry that conforms to the effect on profile of the mean setting parameters that are effective during material removal by the respective cutting edge.
