Abstract
Ultra-precision cutting experiments were carried out using a single crystal diamond (SCD) tool and a poly crystal diamond (PCD) tool for the finish cutting of the tungsten carbide, in order to investigate the influence of the WC particle size and the cutting conditions on the finished surface quality, As a result, although the ploughed dimples remain on the cut surface by PCD tool, the good surface without the defects was obtained in the case of using PCD tool. Furthermore, with a decrease in WC particle size, the surface quality was improved and the roughness reached to 0.01μm (Ra).
