The experimental analysis on cutting tool material is done with referring the established parameters for Cryogenic Treatment. The pilot experimentation is carried out using the Conventional heat treated tool bits as supplied condition and Cryogenic treated tools. The three grades of high speed steel are identified for the investigation purpose and for pilot experimentation H.S.S. T42 grade is selected. The tool material procured is strictly as per the grade specifications for the investigation of effect of cryogenic treatment on tool life. The established parameters for cryogenic treatment are identified referring to previous published research and machining parameters as per the industry specifications. The pilot experimentation using Untreated and treated tools are subjected to turning operation on CNC turning center for a definite work material and machining parameters such as cutting speed, feed and depth of cut are identified. Single point cutting Tool geometry is maintained as per the tool signature and length of the tool is maintained as per the limitations of the machine. The Surface Roughness of the machined work piece is measured using the Taylor Hob-son Surface Roughness tester and the Tool wear is measured using the Tool Makers microscope. The results are tabulated. An experimental effort to understand the effect of Untreated and Cryogenic treated tool on the tool life is the outcome of this paper. The outcome of this paper forms the basis of experimentation using the Orthogonal array for all the selected grades of the material.
