FIELD: metal machining. SUBSTANCE: cylindrical gear wheels with teeth narrowing stepwise from one end to the other are cut by shaper cutter-type tool. In the course of first pass tooth is cut across entire width to a depth corresponding to tooth depth on larger diameter of wheel. Before each next pass radial feed is imparted to one of members and wheel is machined on a part of its width until next step is formed. After that radial feed is imparted in reverse direction. EFFECT: enhanced efficiency. 3 dwg
