【 摘 要 】

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 while machining of In-718, tool wear develops quickly owing to increased cutting temperature and tough bond among work material and the tool, due to its low thermal conductivity and its reactive nature. This review paper also addresses about the issues related to tool material selection, tool coating and insert’s geometry. A better understanding on the propagation of tool wear in different tool materials during turning under various cutting conditions is provided through microscopic analysis. The surface integrity aspects such the surface roughness, micro-hardness variation and induced residual stresses variations against the subsurface depth are also being presented. To summarize, this review paper provides a comprehensive study and analysis of the machinability issues associated with turning of In-718.
