A method for providing teeth on working gears by cutting, wherein the working gear and the cutting tool are driven in rotation at a predetermined speed ratio along axes oriented at an intersection angle. The flanks of the cutting teeth form edges having flank cutting sections arranged on the edges of a gap between two adjacent teeth and extend along a first contour line, and which as a result of an advance in the direction of the working gear engage in a cutting manner to produce teeth having a flank contour predetermined by the shape of the cutting edge. Each of the flank cutting sections is adjoined by a tip cutting section which extends along a second contour line in the region of the base of the cutting tooth gap, wherein the second contour line is curved such that at least partially rounded tooth tips are produced on the teeth.

A method and apparatus for cutting teeth in workpieces, wherein, in a roughing operation, a substantially uncut blank receives rough teeth using a cutting tool having cutting teeth. Operation teeth are produced, the tooth width of which is defined by the spacing between the flanks of the teeth and is greater than the target dimension. In a subsequent deburring operation, a chamfer is incorporated into the end face edge of the tooth flanks, accompanied by the removal of an end face burr. Lastly, in a smoothing operation, the tooth width of the teeth is brought to the target dimension by machining the tooth flanks.
