  • Patent number: 9862020
    Abstract: Method and apparatus for assembling, with fasteners, components of a structure having an outboard side, an inboard side, and a supporting frame. The components are placed together on the frame. An electromagnet having a core with multiple openings is positioned on the outboard side. A magnetically attractive member is placed against the inboard side opposite and aligned with the electromagnet. When activated, the electromagnet is attracted towards the magnetically attractive member and the two hold the components together. Multiple drill members pass through the openings in the core of the electromagnet and multiple openings are drilled simultaneously through the components. Subsequently, multiple rivets or huck bolts are simultaneously inserted into the drilled openings.

  • Patent number: 9862039
    Abstract: A milling tool having multiple cutting disks is disclosed. Each cutting disk is anchored into a flute on the milling tool with clamping screws. During use, the cutting disks naturally become dull. In a preferred embodiment, a single clamping screw is used to hold the cutting disk in place. The clamping screw is loosened and the cutting disk is rotated such that a new and sharp portion of the cutting disk is exposed for use. In an alternative embodiment, multiple clamping screws are used to secure the cutting disk into the flute. In the event a cutting disk becomes stuck in a flute, a clamping screw in a threaded bore coaxially aligned with the locating bore is used to push the cutting disk and eject it out of the flute. This design allows for many positions on the cutting disk to be used before the disk needs to be replaced, sharpened, or refurbished.

    Abstract: Additive friction stir methods for repairing substrates, coating substrates, fabricating/adding/attaching ribs, joining substrates, stiffening and enhancing structures, surface modification, enhancing surface properties, welding, coating, and extrusion are described. An additive friction stir fabrication method and system is described which may be used to fabricate and join a rib to a substrate or to repair a defect in a substrate through extrusion. The method may be carried out with or without the addition of preformed ribs. One such method involves feeding a friction-stir tool with a consumable filler material such that interaction of the friction-stir tool with the substrate generates plastic deformation at an interface between the friction-stir tool and a substrate to bond the plasticized filler and substrate together and extrude this material through a forming cavity to form a rib joined to the substrate. Further described is a system for fabricating a rib joined to a substrate through extrusion.
