In machining, coolants and lubricants improve machinability, increase productivity by reducing the tool wear and extend the tool life. However, the use of cutting fluid in metal working may seriously degrade the quality of environment. Green cutting is becoming increasingly more popular due to concern regarding the safety of the environment and operator health. The experimental investigations were carried out with cemented carbide tool in turning ANSI 304 stainless steel and applications of water vapor, CO2, O2 as coolants and lubricants. The application of water vapor as coolants and lubricants allowed extending tool life. The catalysis chemical reaction have been generated between water molecules (H2O), oxygen atoms (O) of water vapor and fresh metal surface of tool-chip contact region, and multi-dimension metal oxidations which has been formed in tool-chip contact zone weakened mutual action between tool bulk material and chip.
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.
