Abstract: This paper proposed to study the influence of the surface texture on the diamond nanocutting of copper by molecular dynamic analysis, the cases of cutting the workpieces with different surface roughness value (Ra = 0.8 nm, 1.2 nm, 1.6 nm and 2.0 nm) have been discussed. The root causes for the change trend of the cutting force has been explained by observing the change and the motion of the lattice structure in the copper workpieces. The size effect of the surface texture on the cutting force has been analyzed during the whole cutting process, and compare with cutting the smooth surface texture, the analyzing results showed that: the influence of the surface texture is not very obvious, if the surface roughness value is smaller than the critical value; however, its influence will be much more significant, if the roughness value increases to or exceeds the critical value. The mathematical model of the cutting force has been built, and it pretty described the size effect of the surface texture on the cutting force and the nonlinear relationship between the surface roughness and the cutting force.
