Abstract
Superalloy is a high-performance alloy exhibiting certain key features such as better mechanical and creep strength, thermal resistance, surface stability, oxidation and corrosion resistance. Inconel 718 is one among the superalloy possessing hard-to-machine material and mainly employed for greater temperature applications. However, in conventional machining methods owing to its peak strength and low thermal diffusivity superalloy results in poor machinability. Hence, to overcome the above deficiency, unconventional machining processes have been developed and presumed to be a suitable substitute technique for traditional machining methods. Among them, wire electrical discharge machining (WEDM) is a vibrant technique adopted from the principle of electrical discharge machining for machining harder-to-machine materials and also for creating complex-shaped components. The present work deals with the WEDM of nickel-based superalloy with main focus on optimizing the process parameters for machining of Inconel 718 by Taguchi’s response analysis by considering independent process variables such as peak current, pulse on time and pulse off time at three different levels. Based on the results, it was noted that material removal rate (MRR) and kerf width (KW) are key performance indicators and through the experimental analysis influence on each individual process variables on the desired response parameters have been performed.
