Tungsten Carbide Tool Hard Turning Process

A main factor in the hard turning process of tungsten carbide tool is tool geometry or edge preparation.The edge preparation of the cutting tool (round or chamfered edge) affects the cutting forces, cutting temperature, and tool wear. According to Grzesik an extensive study characterizing the surface roughness generated during hard turning with conventional and wiper ceramic tools at a variable feed rate.

A similar study was also reported by Grzesik and Wanat. Their study investigated the surface roughness produced in the turning of hardened low-chromium alloy steel using mixed alumina–titanium carbon ceramic cutting tools equipped with both conventional and wiper inserts. Their results also demonstrated that wiper inserts working with a double feed rate showed similar wear behavior.
