Summary: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.
