摘要：

The pitting damage occurring along preferred crystal orientations observed after single‐point diamond turning of brittle materials dictates a limiting feed rate at which the material can be machined. Using elasticity theory, the orientation dependence of the pitting can be qualitatively explained. Calculations based on a line‐force stress model predict the orientation dependece of the damage symmetry. The results are in good agreement with machining tests for a series of germanium single‐crystal wafers. Copyright © 1990, Wiley Blackwell. All rights reserved
