In the current study, an optimization process of powder-mixed electrical discharge machining (PMEDM) when cylindrically shaped parts made hardened 90CrSi steel is reported. this SiC powder was mixed into Diel MS 7000 dielectric solution. Additionally, graphite chosen as electrode material. The multi-objective functions were minimizing surface roughness (SR) and wear rate (EWR) maximizing materi...

In the present scenario, great effort is expended to improve machining process by adopting multi-criteria decision making in electrical discharge (EDM). this research article, an attempt was made optimize parameters of EDM with Nickel Coated Aluminium Electrode for Titanium Alloy using Preference Selection Index (PSI). The experimental work were performed Taguchi based L16 orthogonal solve mult...

In recent years, several high-performance nature-inspired metaheuristic algorithms have been proposed. It is important to study and compare the convergence, computational burden statistical significance of these metaheuristics aid future developments. This focuses on six metaheuristics, namely, ant lion optimization (ALO), arithmetic algorithm (AOA), dragonfly (DA), grey wolf optimizer (GWO), s...

Concurrent optimization and prioritization of wire EDM parameters can improve resource allocations in material processing should be effective. This study advances the integrated analytic (AHP)-Taguchi(T)-tournament-based-genetic algorithm (tGA) method to moderate influence erroneous allocation parametric analysis decisions electrical discharge machining. The structure builds on AHP-T method’s p...
