Fundamental study on ball end milling of Tungsten Carbide for die and mold

Abstract

Researches have been carried out to develop technologies to machine cemented carbides for dies and molds at high precision and high efficiency. Series of end milling experiments have been carried to machine inclined surface of cemented carbide material with various kinds of ball end mills made of PCD, CBN and diamond coated tungsten carbide. Experimental results are reported here from the view points of tool wear, surface roughness and chip form etc.
