Ultraprecision diamond turning is an important technology to generate a high surface finish in precision components and optics. In this paper, the diamond turning of aluminium single crystal rods with crystallographic axes normal to 〈100〉, 〈110〉 and 〈111〉 is analysed. The effect of the crystallographic anisotropy on the machining of these single crystals is investigated in the light of the mechanics of chip formation, of the cutting force and of the surface microtopography. Continuous chips were formed under all cutting conditions for all of the crystals examined. However, differently orientated crystals exhibit differences in the cutting force and in the quality of the machined surface. The implications of these findings on the improvement of the surface finish that can be obtained in the diamond turned surface are discussed.
