Abstract—In Electromagnetic Forming (EMF) process a sheet metal is situated close enough to a working coil. By discharging the initiallycharged capacitor bank through the coil the workpiece is repelled. This repulsion force originates from the interaction of two magnetic fields; consequently sheet metal forming can be achieved when the workpiece strikes the die.The output of an EMF system strongly depends on the characteristics of the workpiece and electrical parameters. Displacement of the workpiece influences the behavior of the system and the frequency of the applied current affects the performance of the system. Geometrical characteristics of the workpiece which determine the mass and effective area of the workpiece have also considerable effect. The objective of this paper is to study the effect of these parameters on the output of an EMF system. Simulations based on Finite Element Method (FEM) are used to study the (EMF) process and investigate the performance of the system by changing effective parameters. Based on carried out simulations the best configuration of a sheet metal forming system is suggested, which enhances the efficiency of the system and the desired output is achievable.
