Additive manufacturing holds potential for many possible new frontiers in the aerospace industry, and manufacturers in aviation and space flight are reaching for those new vistas. But they’re held back at less than warp speed due to a lack of awareness, unmet technological needs and the absence of a formal regulatory process in their highly regulated industry.

The list of aircraft parts now being made with composites has grown longer than a TSA screening line: the fuselage, empennage (tail section), wings (including skins, stringers, spars, clips, and wing boxes), nacelles, control surfaces (ailerons, flaps), nose skin, and even floor beams.

While still a tiny fraction of the aerospace composites market, the use of metal-matrix composites (MMCs) and ceramic-matrix composites (CMCs) in engine parts has grown substantially over the last few years because they can run at higher speeds and handle more heat.

Manufacturing operations depend on getting the right information at precisely the right moment, ensuring that products get built on time, to quality specs. With the latest enterprise resource management (ERP) software, this critical data flow is often coming via the cloud, as more manufacturers become comfortable with it as a repository for key manufacturing information.

Thread milling, a fundamental metalworking process to create threads, is often the operation of choice when working with difficult-to-machine materials, such as titanium, tool steels, stainless steels, hardened steels and other superalloys.

Known for being a universal and quick process, tapping is the process of making threads in previously drilled holes, and in most cases a tapped hole can be created faster than when using a thread mill. Tapping can generally thread deeper holes in harder materials and any type of machine—a lathe, mill, or drill press—can be used.

Beware predictions of the demise of any technology. If the early 1920s saw the dawn of the optical comparator, there has been much speculation about its sunset. That was especially true when vision systems started hitting their stride a few years ago. Many could see optical comparators were superfluous with the use of vision systems. Many thought the sunset of optical comparators was imminent. Many were wrong. Why?
