Abstract—Metal cutting is a mature technology involving several disciplines of science. It is continuously change in line with strategies of material development throughout the Manufacturing Industries and leading race to provide better tool material and cutting geometries. Recently cutting tool inserts play an important role in hardened state of machining. The advantage of producing components in hardened state can reduce machining cost, lead time and improve surface integrity. Now a days cBN tool insert are considered to be one of the most suitable material for machining hardened steel because of their high hardness, wear resistance and chemical inertness. In this experimental investigation regarding about heat partition, tool life and develop Merchant circle and tool wear of cBN cutting tool and analyzed while turning of AISI316 steel rods.
