Among the metal cutting methods, turning is one of the widely used manufacturing processes in industry. In addition to tool and workpiece material, cutting speed (V), feed rate (f), depth of cut (d) are the most important cutting parameters which highly affect the performance characteristics. It is necessary to select the most appropriate cutting parameters and cutting tools in order to improve cutting efficiency, process at low-cost, and produce high-quality products. Of the present available cutting tools materials, ceramic and cubic boron nitride (CBN) cutting tools are the best candidates and are widely used in turning the hardened steels owing to their high hardness and high melting point. The turning of hardened steels by selecting the right cutting tools and cutting parameters produces surface finishes with grinding quality. The effect of parameters cutting speed, feed rate and depth of cut while turning of AISI 52100 steels are formulated mathematically. A parametric model of cutting tool and workpiece is designed using ProE. Analytical investigations are made on the model by applying the forces by taking different values of cutting speed, feed rate and depth of cut. Analysis is done using Solidworks. Tool life performances of various cutting tools such as mixed alumina ceramic (KY1615 and cubic boron nitride (CBN/TiC) are investigated analytically under different cutting conditions in turning austenised and quenched AISI 52100 steels.
