The increasing importance of machining operations is gaining new dimensions in the present industrial age, all the efforts to be directed towards the economical and quantitatively acceptable manufacture of machined parts. Surface finish is one of the most crucial quality measures in manufacturing products. Customers now have increasingly high demands on quality, making surface roughness one of the most competitive dimensions in today’s manufacturing industry. Stainless Steel (304H) is extensively used material for engineering components. Tungsten carbide tool is common tool used for machining operation of Stainless Steel (304H). Present work is a study of the surface roughness of work specimen during turning operation. The machining is performed with deep & shallow cryogenically treated and untreated tool bits used in turning process. In present work full factorial experimentation approach is applied to study the impact of machining parameters on the surface roughness of turned workpieces using cryogenically treated and untreated tool. The study presents a comparison between the machining performances of deep, shallow cryogenically treated and untreated tool bits with a methodology to achieve optimum selection of machining parameters and bit nose radius for CNC turning operations and describe the interrelationships between machining parameters and surface roughness during operation. The results indicate the treatment done cryogenically on the material improves the hardness of the material. In this work, a comparison has been done for the machining performance of deep & shallow cryogenically treated, and untreated tool bits.
