Progress and Challenges Related to Thermal Fatigue Research of Super-hard Cutting Tools

Abstract

A large number of super-hard tools literature has been studied, most of which aimed at tool wear patterns and mechanisms. Researches on thermal lord affecting tools wear are carried out insufficiently and achievements about thermal cracks initiation, propagation are little reported. As existing of elevated temperature and intense heat during cutting processes, super-hard cutting tools thermal fatigue problems are obliged to be faced and some fundamental and unresolved issues need to be answered.
