ABSTRACT:
A method for forming a connector contact in which a workpiece is punched by a press to form a contact surface which includes steps of forming a provisional contact surface by a first punching operation of the workpiece, and forming a final contact surface by shaving the provisional contact surface. The provisional contact surface is subject to a split-shaving operation from the front and rear sides of the workpiece to separately shape the top and bottom halves of the provisional contact edge in the direction of the thickness of the workpiece to form the final contact surface.
