Abstract
A method of forming a structural member includes hydroforming the blank to form a hydroformed member and finishing the hydroformed member by positioning the wall of the hydroformed member between a die surface and an electromagnetic discharging element having a non-circular cross-section, and actuating the electromagnetic discharging element so that the metallic wall of the hydroformed member presses against the die surface.
