A new method of making chip grooves on end mills

A chip groove is processed by a special shaped disc cutter, whose tooth profile fits only a particular end mill standard size. The paper analyzes the formation of chip grooves on end mills. Complex profile disk cutters are proposed to be replaced with double-angle disc cutters. Guidelines on choosing TU 2-035-526-type double-angle disc cutters to provide groove profiles very much like the recommended standard ones are given. To obtain the desired groove profile, not only the profile angle should be chosen, but also the double-angle disc cutter should be installed in a certain manner relative to the workpiece. Numerical techniques for calculating the required profile angle of a double-angle disc cutter and installation options for several types of end mills are described.
