Abstract
PURPOSE: A manufacturing method of a roughing cutter for the work of rough machining in which nick-shaped rakes 2 are provided in a cutting edge 1 of a built up end mill.
CONSTITUTION: A nick is machined as a setting θ±γ when a cutting edge is developed, and set to an optional degree of the side clearance angle α(β±γ) in a main cutting corner after being built up in the groove of a main unit helix angle θ. That is, to give the side clearance angle α in a main cutting corner larger than a helix angle β of the nick by γ, the set angle of the cutting edge is determined to θ+γ, and each cutting edge is arranged at an equal space πD/N on a developed plane with πD as a developed width, and on the plane a plane nick cutting in lines n=(N-K) is performed to machine the nick for a cutting edge. The machined cutting edge is inserted into the groove of the main unit with the helix angle θ and constructed.
