Abstract: A system includes a robotic arm, a rotisserie control linkage, and a computer system. The robotic arm includes a touch probe and laser head. The rotisserie control linkage is configured to couple to a transport cart. The computer system is communicatively coupled to the robotic arm and the rotisserie control linkage and is configured to control the system to probe, using the touch probe of the robotic arm, a transparent outer layer of an aircraft canopy located on the transport cart in order to determine surface measurements of the aircraft canopy. The computer system also controls the system to ablate, using a plurality of predetermined parameters and the laser head of the robotic arm, an interface layer located between the transparent outer layer and the aircraft canopy, wherein movements of the robotic arm during the ablation are based on the surface measurements.

Abstract: An apparatus for precision shaving is provided. In one embodiment, the apparatus includes an endmill cutter, a base frame, and a motor adjacent to the base frame and having a shaft on one end. A coupler is positioned between the shaft and the endmill cutter. A positioning slide is housed within the base frame and a coupler frame and a first gear are fastened to the positioning slide. A second gear is adjacent to the first gear, the second gear having a set of first teeth and a set of second teeth positioned opposite the set of first teeth. The set of first teeth and the set of second teeth are separated by a gap.

Abstract: A system includes a laser configured to conduct a cleaning cycle that includes producing a laser beam capable of cleaning a faying surface of each of a plurality of nutplates, and conducting a first pass to clean each of the faying surfaces, wherein the laser is at a first position having a first angle relative to an axis orthogonal to the faying surfaces during the first pass. The system also includes a nutplate tray configured to hold the plurality of nutplates such that each faying surface is oriented such that the laser beam is capable of contacting each faying surface at least once during the cleaning cycle.

Abstract: A system includes an abrasion assembly containing one or more abrasion pads configured to clean a faying surface of multiple nutplates, and a shaft attached to at least one of the abrasion pads and configured to rotate some or all of the abrasion pads during cleaning, wherein cleaning includes abrading the faying surfaces with the abrasion pads. The system also includes a base configured to attach to a pressure applicator, and a pressure applicator configured to attach to the base, hold the nutplates such that the faying surface of each nutplate is capable of contacting one of the abrasion pads, and apply pressure to the nutplates such that each of the nutplates contact one of the abrasion pads during the cleaning. Furthermore, the abrasion assembly is configured to rotate the abrasion pads within at least one of the base and the pressure applicator during cleaning.
