Residual stress is an important factor in machining process an attempt has been made to analyze the residual stress in turning of AISI4340 steel. The residual stresses that can be found in a cutting tool insert are mainly generated at the final step of the machining process. Feed, speed, depth of cut are the input parameter. The residual and the tool wear are the output responses. Cryogenic treatment will improve the performance and made significant of wear resistance, better residual stress and product quality of cutting tool. This is the study of review the literature from performance of cryogenically treated cutting tool insert in varying nose radius and the soaking period. The level of the generated residual stress depends on the machine materials and on the process parameters used. The overall goal of the present paper is to identify an analytical relationship between residual stress and turning process parameters accounting also for the material being machined.
