Abstract
A method for forming a metal beam may comprise: clamping first and second portions of the metal beam in a substantially fixed and in a position whereat the metal beam is rotatable about three axes; applying a net bending force to the clamped second portion of the metal beam at a predetermined angle; sensing twisting of the second portion of the metal beam resulting from the net bending force; and modulating the angle at which the net force is applied to reduce the twisting of the metal beam. As a result, the net bending force is moved toward the shear center and toward being along the principal axis of the metal beam.
