Abstract
A fine blanking cam die for removing a slug from a workpiece includes an axially moveable punch, laterally moveable cam dies and a driver engaged with at least one of the cam dies. The laterally moveable cam dies define an aperture to receive the punch. Movement of the driver causes movement of at least one of the cam dies such that a side force is applied to a slug of material being formed as the punch travels through the workpiece.
