Embodiment Construction

[0031] [0031] first reference Figure 1-Figure 3, embodiments of the present disclosure relate to methods and manufacturing processes for assembling and attaching parts or parts assemblies. As used herein, the terms "part" or "assembly of parts" are intended to include numerous structures and components to be assembled and / or joined together, and may also include individual parts, assemblies of parts or accessories. The method is particularly useful in the assembly of relatively large and complex parts or assemblies of parts where there are gaps or spaces between the parts being assembled that need to be filled with shims. In the illustrated embodiment, the parts comprise large assemblies used to build aircraft, however, it should be understood that the present methods and processes may be used and adapted for a variety of other types of part assemblies for a wide variety of applications.

[0032] [0032] Commercial aircraft 20 are typically manufactured by assembling large, m...

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 maybe modified to reflect the effect of part assembly fit on performance characteristics of the aircraft.

Description

technical field [0001] [0001] The present disclosure relates generally to manufacturing processes for joining parts, and more particularly, to methods for assembling, aligning, and joining large and complex assemblies of parts. Background technique [0002] [0002] To compensate for dimensional changes, spacers are commonly used in the assembly and assembly of parts and accessories. In the aircraft industry, spacers are used extensively for assembling and joining fuselage sections, and for attaching wing and tail assemblies (vertical and horizontal tail assemblies) to the fuselage. Shims (sometimes called shims) are used to fill spaces between joined components that can be caused by tolerances in the parts themselves. Utilizing spacers to fill the space between mating surfaces on the part assembly results in a more structurally reliable aircraft. Shims are also used to properly align the parts. [0003] [0003] The design and manufacture of specific gaskets for each aircraf...
