Cutting heat is a kind of important physical phenomenon during the metal-cutting process, which implies a temperature increment in the cutting area. This temperature and its distribution can affect the cutting forces, chip deformation, tool wear, and finished surface quality. For the particular cutting conditions, the temperature depends on cutting speed. The major part of energy spent during high-speed cutting (HSC) is converted into heat energy, with a small share being stored in the deformed materials [1-3].
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
