Aluminum–SiC particle composites (particle diameter: 0.4, 5μm; volume fraction: 0.6, 15%) were machined by dry turning using monocrystal diamond tools with different crystal orientation. In the (100) tool, the rake face was parallel to (010) plane and the direction of depth of cut was inclined by 5° from [100] toward [010]. The (110) tool was obtained by turning the (100) tool by 45° about [001] axis. Sharpness of cutting edge of the (100) tool was lost locally during machining because of large-scale chipping, the machined surface was quite rough. In the (110) tool, on the other hand, wear occurred nearly parallel to the rake and flank faces, and hence cutting edge was kept sharp. Although tool wear became more severe with increasing size and volume fraction of SiC particles, fine machined surface was obtained with this tool even in a composite with 15 vol%SiC particles of 5 μm in size. It is concluded that (110) tool is superior to (100) tool from a viewpoint of both tool wear and roughness of machined surface.
