Abstract
A method for cutting teeth into working gears using a tool, the tool main part of which has a plurality of cutting teeth which are arranged about a rotational axis and which protrude radially from the tool main part, the cutting teeth forming an end face, two tooth flanks which point away from each other, and cutting edges. The cutting edges are formed from the tooth flank edges adjoining the end face. In a first method step, tooth gaps which form tooth flanks are produced in the working gear by means of the cutting edges using a machining process in a first position of the tool relative to the working gear, and in a second method step, the working gear tooth flanks produced by the cutting edges are fine-machined by an abrasive tool surface.
