Abstract: Shims used to join part assemblies are automatically designed and fabricated without the need for fitting part assemblies together in order to determine the exact dimensions of voids filled by the shims. The locations of key features on part assemblies are surveyed using a merged photogrammetry and laser tracking technique that generate the dimensions of a virtual shim. The dimensions of the virtual shim are contained in a digital file that can be used to automatically fabricate the shim using automated fabrication equipment such as a CNC machining center. The automated virtual shim design may be modified to reflect the effect of part assembly fit on performance characteristics of the aircraft.

Abstract: Apparatus and methods of creating sketch-based eggcrate substructures for manufacturing composite parts are disclosed. In one embodiment, a method of creating a design includes providing an input model from a plurality of inputs, including providing a layout geometry, and providing a specification data structure. A resolution model of the input model is created, including interpolating the layout geometry, and interpolating the specification data structure. The method further includes finalizing a layout using the resolution model, and providing one or more solid components into the finalized resolution model to create the design. Embodiments of the invention enable rapid configuration of designs either interactively, non-interactively, or through combinations of both, and may reduce the time, labor, and expense associated with the development of such designs.

Abstract: An apparatus and method of creating a sketch-based eggcrate substructure for manufacturing composite parts, includes creating an input model from a plurality of inputs; launching a batch job using the created input model; and obtaining an output model by running the batch job, or running the program interactively using the input model and obtaining an output model.
