  • Penetrator and method of manufacturing same
    Patent number: 9199299
    Abstract: Penetrators and methods of manufacturing penetrators are disclosed. One method of manufacturing a penetrator having arrowhead geometry and base geometry includes the steps: (a) cold heading a piece of material to form a blank; (b) machining the blank to create the arrowhead geometry; and (c) roll forming the blank to create the base geometry. Another method of manufacturing a penetrator having arrowhead geometry and base geometry includes the steps: (a) machining a piece of material to create the arrowhead geometry; and (b) roll forming the piece of material to create the base geometry. Yet another method of manufacturing a penetrator from a blank includes the steps: (a) machining the blank to create a first surface feature of the penetrator; and (b) roll forming the blank to create a second surface feature of the penetrator.
