The Comprehensive Review on machining of Inconel 718 superalloy

Abstract

Inconel 718 is nickel based alloy, difficult to machine and precipitate which having tremendous mechanical properties. It has outstanding features like high shear strength, low thermal conductivity, potential to sustain its strength and hardness at prominent temperature. It plays a crucial role in various manufacturing applications for instance aircraft, defence, aviation and gas turbines. Numerous efforts have been to produce to the workability of Inconel 718 indifferent operating conditions; different tool electrodes and tool geometry. The main objectives which are focused in this review study are drilling, milling and turning. Finally, a brief idea of non-traditional cutting fluid over traditional cutting fluid is also discussed.
