Feasibility Assessment of Novel Maglev Dry-EDM by Machining Aerospace AI-6062 Alloy
Department of Mechanical Engineering, Indian Institute of Technology (ISM), Dhanbad, Jharkhand, India
ABSTRACT
In the current scenario, manufacturing through EDM process is a prominent technique for achieving desired complex micro/nano features on any product. The current work aims to check the feasibility of the novel Maglev EDM for machining aerospace Al 6062 alloy. The novel setup utilizes the combined effect of permanent and electromagnet to diminish arcing and short-circuiting. The set control parameters were 28 V open-circuit voltage and 1.5 A peak current while maintaining a duty factor of 95.5%. The measured discharge voltage and discharge current were 23 V and 700 mA respectively. Brass rod (ø = 2.2 mm) and surrounding air were used as tool and dielectric media for the experimentation, respectively. Further, the machined surface of the workpiece has been analyzed using highresolution microscopy and 3D surface profilometer. The newly developed Maglev EDM feasibility to machine aerospace Al 6062 alloy has been confirmed in the present work with an average MRR of 0.403 mg/min.
