The machining industries are always looking for a process of machining which provides high quality dimensional accuracy in the work piece surface finish high production rate tool life and economy The Computer Numerical Controlled CNC machines play a major role in modern machining industry to improve the product quality as well as productivity Turning is the primary material removal process from the surface of a rotating cylindrical work piece Stainless steels are used in aerospace automotive marine applications and in the manufacture of surgical instruments springs valves shafts ball bearings turbine equipments petrochemical equipments etc because of their resistant to corrosion high temperature oxidation and maintenance of their mechanical properties over a wide range of temperature Stainless steels are generally difficult to machine due to their high tensile strength high ductility superior work hardening rate low thermal conductivity and abrasive character This combination of properties often results in high cutting forces temperatures and tool wear rates as well as a susceptibility to notch wear chip breaking difficulties built up edge formation and poor machined surface finish A collection of papers related to this topic is there but little empirical studies have been conducted on the issue of responses The most essential parameters which are affecting the quality of turning operation are cutting tool related parameters newline%%%reference p189-203.
