?Review of Different Approaches to Improve Tool Life?

S.V. Kadam, M.G. Rathi

Machining without the use of any cutting fluid (dry machining) is becoming increasingly more popular due to concern regarding the safety of the environment. Because of this demands for increasing tool life without use of coolants are arising. This paper is an attempt to review the different techniques employed to improve the tool life. The paper begins with reviewing tool wear, different methods to measure wear, and different approaches employed to improve tool life such as tool geometry, machining parameters, edge honing, and thin film coating.
