Abstract

PURPOSE: To facilitate setting of the angle of cutting edges of a roughing cutter by a method wherein the main cutting corner side relief angle of nicks after building- up can be set at an arbitrary angle.
CONSTITUTION: A built-up roughing cutter with an outside diameter after building- up D, the number of cutting edges N, the axial pitch of nicks Pa, and a desired side relief angle for main cutting corner α, is produced as follows. The N pieces of cutting edges are developed on a plane; the cutting edges 21W24 are arranged at a pitch of S/N, notwithstanding the fact that the pitch after building-up is πD/N, and nicks are machined by plane nick grinding along n(=N-K) lines. With the nick machining stopped at the positions indicated by arrows 10, 20, 30, and 40, the cutting edge lies in the portion surrounded by a closed line abcd. The side relief angle α after building-up can be set at an arbitrary angle by determining the desired value of α and selecting the developed width S based on the relationship α= tan-1(n.Pa/S).
