Need for an efficient cutting tool and machining techniques are the prime requirements of modern machining industries. Certain domains such as defense, aerospace and automobile use the typical ‘difficult to cut materials’, which has specific applications. Materials’ machinability, tool life, surface finish achieved by the machining process, factors affecting surface quality and tool life are the key areas of investigations that researchers are focusing on. In this paper two difficult to machine materials namely Inconel 718 and Stellite 6 have been experimentally investigated for their machining characteristics. The effect of Flood and Jet cooling techniques on the machinability of these materials have been compared with dry machining, having a focus on tool wear, surface roughness, cutting temperature and cutting vibrations.
