Fundamental study on end milling of Tungsten Carbide for dies and molds

Effect of cutting speed on tool wear

Abstract

In order to establish an efficient machining method of Tungsten Carbide for dies and molds, the authors have carried out series of turning experiments of tungsten carbide by employing various kinds of PCD tools and CBN tools, and investigated the fundamental cutting performances from the view point of the tool wear. In the present research, high speed milling experiments of tungsten carbide have been carried out. The effects of the cutting speed and others on the tool wear are presented here.
