Abstract: Nickel-base super alloy- Inconel 718 is a high strength, thermal resistant alloy in recent years because of its excellent mechanical properties both at cryogenic and elevated temperatures. It is used in aerospace, petroleum and nuclear energy industries the hardening characteristics and toughness of INCONEL 718 makes machining difficult and increases cost of manufacturing. Hence, it is difficult to cut material The challenge for manufacturing engineers is to reduce the machining cost of INCONEL 718 without effecting the surface finish and hardness of the material. This project presents the result of effect of machining parameters on the surface finish, hardness and impact of residual stresses on Inconel-718. The effect of machining parameters on the surface hardness was investigated by conducting nine experiments using CNC lathe. The machining parameters considered were cutting speed, 300
