The Cutting Edge of Aerospace Manufacturing: Sheet Metal Fabrication Technology

The construction of intricate forms in aerospace engineering is both essential and difficult, and the necessity has been ably met by recent advancements in sheet metal construction. Specifically, these advancements have taken the form of CAD/CAM software that no doubt most of the readers of this book are familiar with. However, the software’s innovations have permitted the designers of aerospace structures to execute their visions in a wholly unprecedented manner—by "assembling" component parts in a way that, at least for the moment, can be seen as tongue-in-cheek homage to the Huey helicopter's assembly process in Vietnam. Of course, the software's designer can be seen as the architect of a spacecraft’s structure in much the same way that a helix can be viewed as cylindrical.
Using CAD/CAM software in sheet metal fabrication catapults the manufacturing process into a whole new realm. With this software, designers and engineers can work in fluid creation "processes," where they can virtually "try on" various design ideas before committing to them in production. As I mentioned before, waste reduction (and the reduction of the need for prototypes) is one of the major advantages of CAD/CAM in fabrication. To say the same thing in a different way, the excellence of the software's final product is only matched by the excellence of its ability to avoid the very sorts of mistakes that lead to environmental and economic waste.
The stalwart sheet metal fabrication machines are CNC machining centers. Working directly from the CAD/CAM software's commands, they carry out the orders with great precision and speed. That's not to say my good work won't make itself visible on the other side of the CAD/CAM equation. The components must fit together and be seen from a half-mile up in the sky with the same vanity as any other work of art. Still, I cannot sugarcoat it: The CNC machine is really the only tool worthy of producing the surface of an aerospace part with any level of confidence. The machine's faithful execution of my commands really ought to be the end of the story, but alas, it's only the beginning.
Sheet metal fabrication is a time-honored, crucial manufacturing process in the aerospace sector. It meets the challenge of forming and assembling the slender, strong, durable, and lightweight components integral to aircraft and spacecraft. Continuous innovation keeps this process and its materials in step with the requirement for ever-more efficient use of energy and materials—an overall migration toward truly sustainable manufacturing. In sheet metal fabrication, as in all aerospace manufacturing, composites and superalloys are the key advanced materials. And the use of robots in this process is also an innovation that promises to enhance fabrication's efficiency and overall effectiveness even further.
These developments in sheet metal fabrication have an influence that goes far beyond the aerospace field. They bring to the manufacture of many components in all sorts of systems the benefits of precision, efficiency, and reliability. That is what promises to make the advances truly revolutionary. Yet what makes them even more potentially disruptive to traditional ways of thinking about manufacture is the melding of design and production that the new processes make possible. That promises to produce unprecedented levels of innovation. And sheet metal technology, partly because of its ubiquity in the manufacture of all sorts of systems, is well placed to play a pivotal role in that unfolding revolution.
