摘要

A method for machining of tooth flanks by grinding or milling respectively as to internally or externally toothed workpieces with a profile disk tool in a discontinuous indexing process. For generating flanks with complicated flank modifications it is proposed to perform during machining besides the known movements an additional movement that is composed of at least two portions, extending in different axes of the machine, whereby the individual portions are so matched that a prescribed distortion of the flanks results. There are embodiments for single flank processes and for double flank processes. It is also possible to generate topological flank modifications and flanks, of which certain parts are set back relative to the unmodified area of the flank. Basis for determining the tool- and workpiece setting data and the movements that the tool has to perform relative to the workpiece, is a simulation of the machining process on a computer.
