In this investigation, the effects of cryogenic soaking time on cutting insert were investigated. Cryogenic treatments were carried out at -196°C for various soaking times of 12, 24, and 48hours followed by tempering at 200°C for 2hours. The Scan Electron Microscope image and X-Ray Diffraction pattern analysis validate the structure of η-carbide on the surfaces of the inserts. The hardness result revealed that the deep cryogenic treatment improved the surface rigidity of the inserts. The speed, feed rate and depth of cut are preferred as input parameters of the experiment. The out response of the tool wear is measured the flank wear of the inserts. As a result, increase in soaking time of deep cryogenic treatment imports superior tool wear resistance of the inserts.
