Machining, Fabrication and Inspection of Empennage Final Assembly Jig
(Click on thumbnail to enlarge)
West Cobb Engineering And Tool Inc. is at the forefront of aerospace tool design, and one of our specialties is fabricating large aircraft assembly fixtures, such as the one pictured here. Used for securing the major components and modules for accurate, true, and square assembly of the fuselage of a large transport plane, precision quality construction was critical to achieving the unforgivingly tight tolerance requirement of the aircraft assembly operation.
Using multidisciplinary engineering software gave us a full spectrum of tools for designing an ergonomic and productivity-enhancing solution for this complex assembly structure. Featuring overall dimensions of 28.5' in length, 6.5' in width, and 14.0' in height, we constructed it from steel and aluminum tubing and applied MIG welding techniques to produce deeply penetrating defect-free joints. We utilized a laser tracking system to measure the spatial geometry with pinpoint precision and resolution to verify the dimensional positional accuracy of ± 0.005".
Our engineers and programmers have been involved with many aircraft projects, and our integrated approach to this design and build project enabled us to meet our commitment to the customer in terms of cost, schedule, and technical performance.If you are interested in learning more, Contact us today.
