Parametric Study for Surface Quality on Magnetic Force-assisted Powder-mixed EDM

Ram Sajeevan and Avanish Kumar Dubey

Abstract

As per the demand of high-tech industries, advanced developed metal matrix composites (MMCs) and alloys came into the force due to their high strength to weight ratio but the machining of these advanced developed materials facing a tough challenge due to the hard reinforcement with a matrix material. This structural arrangement is difficult-to-cut during machining by traditional machining processes (TMPs), so people move towards non-traditional machining processes (NTMPs). Electric Discharge Machining (EDM) process is one of the popular NTMP for such materials, but it has a low machining rate and poor surface quality, so to overcome these drawbacks, researchers are working on the hybrid concept with EDM for the improvement of machining characteristics. This research article is devoted to the experimental investigation of Magnetic Force-assisted Powder-mixed EDM (MFPEDM) and its parametric study for micro-hardness, recast layer thickness, and micro-cracks density and concluded that the current, pulse-on time and powder concentration are the most significant controlling factors for machined surface integrity.
