✦ Synopsis

In this paper, the surface generation in ultra-precision diamond turning of Al6061=15SiC p metal-matrix composites was investigated based on di erent analytical approaches which include parametric analysis, cutting mechanic analysis, ÿnite element method (FEM) analysis and power spectrum analysis. Parametric analysis was performed to explore the in situ inter-relationships between the process parameters and the surface roughness. The surface properties of the diamond turned surface were extracted and analyzed by the power spectrum analysis of the surface roughness proÿles. Di erent surface generation mechanisms were deduced based on the cutting mechanics and FEM analysis. The results of the theoretical analyses were veriÿed through a series of cutting tests conducted under various cutting conditions and a good correlation between the theoretical and experimental results was obtained.
