Abstract
Ultra-precision cutting of cemented carbide was performed using sintered diamond tools to study the effects of very fine cuts and the feed rate on the cutting characteristics and the properties of the finished surface. The study revealed that, although cutting at a low feed rate of approximately 1 μm/rev reduced the finished surface roughness of cemented carbide, gouge-like Co was exposed in some positions on the surface. In addition, it was found that defects in the finished surface could be diminished by reducing the nose radius of the sintered diamond tool.
