Abstract

Tool life of a cutting tool is dependent on many parameters such as tool material, machining conditions and work material. The main aim of this study is to analyze the differences in tool performance between deep cryogenically treated and untreated tool steel during orthogonal turning of C-45 steel. The Deep Cryogenic treatment has been carried out on M-35 tool steel at -1930C. An improvement in tool life has been found on Deep Cryogenically treated M-35 tool steel due to morphological changes that takes place in the tool material, which helps in decreasing the amount of force and power required for turning operation at the cost of friction. Also helps in improving surface finish of work material. This paper describes a study on the effect of Deep Cryogenic treatment of M-35 tool steel.
