Wear mechanisms of single-crystal diamond tools in ductile machining of reaction-bonded silicon carbide (RB-SiC) were investigated. It was found that tool wear could be generally classified into two types. One is microchippings on the cutting edge, which were induced by micro impacts between the cutting edge and SiC grains. The other is two kinds of gradual wear patterns on flank face caused by different mechanisms: non-periodical scratches caused by scratching effects of the SiC grains, and periodical grooves caused by transcribing effect of tool feed marks on the machined surface. A tool-swinging cutting method was proposed to improve the service life of diamond tools.
