Turning is a machining process where steel tools are the materials generally used in tool bits. There fore tool material properties have a major impact on the turning operation. Enhancement of tool steel properties will improve machining. Present work deals with the process of deep cryogenic treatment (DCT) done on a high speed steel tool bit with a single cutting edge. This enhances the machining of different work piece materials having good surface finish with increased tool life. The turning has carried out at a constant depth of cut(DC) and feed rate(F) on a commercial tool having material of SS304 using both cryogenic treatment(CT) and also non- treated high-speed tool steel bit sat at three variable speeds with an interval of 03 minutes up to the tool bit nose fracture is achieved. From the results, graphs were drawn for wear and the time at each speed, and evaluate those results with tool life finally it is observed that the CT has resisted more time when compared to a tool with non cryogenically treated(NCT) at a given speed with increasing tool life. Using the cryogenically treated(CT) tool, the turning parameters of feed(F), speed(S) and depth of cut(DC) at three levels were considered and using the design of experimentation, L9 orthogonal tool array was taken to find the optimized parameters in the turning of SS304. The response of the cutting parameters on flank wear (FW) and surface roughness(SR) was done using ANOVA in MINITAB and the interaction plots were plotted.
