In order to improve productivity and product quality and reduce cost, over the past many years, producers made great efforts to find the new method of chamfering. One of the methods is the chamfer milling cutter, on the milling machine tool. This method is suited for medium and small batch production. The tool life is long, the machining quality is stable. In this paper, the principle of meshing between gears and rake is applied. The design principle and calculation method of the chamfer milling cutter is put forward. This paper also made some computer simulation (C) 2012 Published by Elsevier B.V. Selection and/or peer-review under responsibility of Garry Lee
