Abstract

Simple techniques for an assessment of the depth and intensity of plastic work, or sub-surface damage, in single point diamond turned components are described. Based on microhardness measurement techniques, the approach outlined here gives good qualitative correlation with conventional metallographic approaches for sub-surface damage assessment. Some data indicating variation of sub-surface damage with changing process parameters is presented; the aim of the paper, however, is to outline possible test methods and stimulate discussion. Possible approaches to measurement of tool sharpness are also discussed, again with the aim of eliciting comments.
