  • Patent number: 9983566
    Abstract: Systems and methods of inspecting a manufactured part include creating a computer model of the part with a desired model contour having a model feature at a desired location. The manufactured part is scanned to obtain scanned data indicative of a manufactured surface formed in a manufactured contour and having a manufactured feature at an actual location on the manufactured surface. The computer model is modified using modeled reaction forces so that the model contour matches the manufactured surface. A determination whether the manufactured part is acceptable is based on a comparison of the actual location of the manufactured feature with and the desired location of the model feature with the model surface in the modified model contour. Additionally or alternatively, the reaction forces are compared with a reaction force threshold to determine whether the manufactured part requires reworking.

  • Patent number: 7194326
    Abstract: Methods and systems for large-scale airframe assembly are disclosed. In one embodiment, a method includes measuring a plurality of discrete point positions at least one of on and adjacent to at least one of a first and a second component, and measuring at least one surface position on the at least one of the first and second components. The measured positions are compared with a desired position information (e.g., a computer aided design model). The comparison may include applying a fitting routine to the measured positions and the desired position information. Next, a transformation matrix for improving the comparison between the measured positions and the desired position information is computed. At least one of the first and second components is then moved according to the transformation matrix. During movement, the plurality of discrete point positions may be monitored and provided to the position control system by a feedback loop.

  • Patent number: 6901673
    Abstract: There is provided a tie-in device for correlating at least two different coordinate systems. The tie-in device comprises an outer surface having a predefined geometric shape, such as a generally spherical surface, located at a first predefined distance from a reference point of the tie-in device, such as the center of the generally spherical surface. The outer surface of the tie-in device is mappable to determine the location of the reference point in a first coordinate system. The tie-in device comprises at least one target located at a second predefined distance from the reference point. The target is locatable in a second coordinate system to determine a location of the reference point in a second coordinate system. The relative locations of the reference point are tied-in, advantageously by processing circuitry, to correlate the first and second coordinate systems.
