A Calculating Method of Cutting Edge Profile of Hobs (4th Report)

Allowable Angles for Circumferential Form Relief and Side Relief

Abstract

When the values of coordinates and gradients at some points on a work tooth profile are given, we can calculate the hob tooth profile analytically. In this report, the calculating method of allowable angles for the circumferential form relief and the side relief to the given hob tooth profile is described. By this method, we can know easily whether sufficient relief angles can be obtained or not.
