<ul><li>Grumman Aerospace made a breakthrough in forming metal parts using electromagnetic forming techniques several decades ago.</li><li>The technique involved using electromagnetic forces to squeeze metal tubes with gear-like fittings, resulting in parts that are stronger, lighter, and more fatigue resistant.</li><li>The process of EMF torque tube production includes placing a tube inside a coil, installing the end fitting, and generating a strong electromagnetic field to drive the tube inwards, forming a strong joint with the end fitting.</li><li>The technology was licensed to Boeing and proved to be highly successful, with the video on the development of the Grumman EMF Torque Tube showcasing the innovative technique.</li></ul>
