An effort has been made to study the cutting conditions and cutting parameters impact on work and tool material during turning of Inconel-718 (In-718) super alloy. The present discussion would be helpful for understanding the machinability aspect such as surface integrity, cutting forces, work hardening, tool wear, and tool life while turning In-718. It is being reported that while machining In-718, tool wear develops quickly owing to increased cutting temperature and tough bond between the work material and the tool, due to its low thermal conductivity and its reactive nature. Uncoated carbide tools performed well for a cutting speed range of 10-30 m/min, and for speeds more than 40 m/min, coated carbide inserts are suited for machining In-718. This review paper also addresses the issues related to tool material selection, cutting environment, tool coating, and insert geometry. Flood cooling system reduces the cutting forces generated during machining and also results in lesser microhardness on the surface of the machined components. Emulsion coolant technique provides better surface than cryogenic cooling system but for better tool life cryogenic cooling system is preferred. © 2019 University of Kuwait. All rights reserved.
