Abstract: Wire-electro discharge machining (WEDM) has emerged as a crucial non-traditional machining technique since it offers a practical approach for manufacturing components made from challenging materials such as titanium and zirconium, as well as for creating complex shapes that conventional machining methods cannot achieve. In this study, an experimental analysis has been conducted to assess how the parameters of Wire EDM influence the performance characteristics. A medium carbon steel AISI 1040 was chosen as the workpiece for this investigation due to its elevated ultimate tensile strength and hardness. The Wire EDM parameters for the experiments were organized according to the L16 0A design, using brass wire as the electrode and distilled water as the dielectric fluid. The results of AHP with utility analysis revealed that wire tension is the most influencing factor in achieving better multiple responses.
