Abstract

Based on the anisotropy of granular structure, the reasonable criterion was given to understand the generation of the prior cleavage or slip for each cleavage system or slip system. The phenomenon that the roughness of the diamond turned single crystal materials's surface distributes in scallop is explained, and a turning method is presented to eliminate the scallop distribution. Beside this, the AFM was used to observe the micro-topography of the light and shade area of brittle single crystal material's diamond turned surface. The criterion is in good agreement with the observed results.
