ABSTRACT:
A method of using an electromagnetic forming machine to hem a panel assembly includes providing an inner panel and an outer panel. The outer panel has a plurality of flanges and a plurality of relief areas. An electric forming machine is provided having a coil for discharging electric energy to generate a magnetic field. The inner panel is positioned such that portions of the outer edge of the inner panel are aligned with the flanges of the outer panel to form a loose assembly of panels. The loose assembly of panels is positioned proximate the electromagnetic forming machine such that the coil surrounds the flanges and is disposed substantially coplanar with a plane formed by the relief areas. The electromagnetic forming machine is activated to generate a magnetic field causing the flanges to bend over.
