Design and Fabrication of Magnetic Field System for Improving EDM Process
Keywords:EDM, MF-EDM, Magnetic field system, Design and construction, Optimization
Electric discharge machining is one of the non-traditional machining methods. In this process, many of the limitations of traditional machining methods have been removed, which is why the use of EDM in the manufacture of industrial parts and molds has greatly increased today. However, electric discharge machining has low efficiency and high energy consumption, and the quality of the machined surface in this method is low. For this reason, researchers have always been trying to find a way to increase the efficiency and quality of the surface. One of the most effective methods is the application of external magnetic field in electric discharge machining. Applying a magnetic field around the machining range in EDM leads to increased machining efficiency, reduced tool corrosion, increased chipping rate, reduced surface roughness and improved surface integrity. Previous research has shown positive results from magnetic field applications, but so far, no mention has been made of how to design a magnetic field application system. Undoubtedly, building an efficient system to apply the magnetic field in EDM is a challenges of using this method. In this article, using previous research, experiences gained and scientific foundations of a method to build this system will be presented.
