U.S. manufacturers have faced significant headwinds this year: supply chain problems, a skilled labor shortage, inflation, and the war in Ukraine. And yet despite these issues—or perhaps, because of them—manufacturers continued to invest in people, plants and equipment.
Manufacturing in the age of Industry 4.0, digitally connected machines and smart factories require a new breed of engineers who are equipped with a fresh set of skills. That’s why Arizona State University recently launched the School of Manufacturing Systems and Networks.
To automate an assembly task that requires two hands, engineers have two options: one robot equipped with a tool changer or two robots. Now, there may soon a third option. We have developed a single end-of-arm tool that can simultaneously hold a part, such as a dowel or a long screw, in place and install it at the same time.
Composite structures in airplanes are often thin-walled and lightweight, resulting in significant compliance. This presents a challenge for handling and assembly.
The current paradigm of car manufacturing, which provides a variety of models, colors and options, is called mass customization. However, mass customization is now transforming into mass individualization. In mass individualization, products are uniquely catered to consumers’ desires. For example, some car buyers may want to replace ordinary car seats with luxury brands, such as Louis Vuitton, to differentiate themselves.
Rotor blades, guide vanes and other components for jet engines are made from costly materials and machined to precise tolerances. Such components are typically made in batches, due to the time involved in setting up machine centers. The process also requires a fair number of people to tend the machines and assist in changeover.
The biggest challenge in automatic screwdriving isn’t speed or torque accuracy: It’s getting the fastener to the tool reliably and oriented correctly. Fortunately, assemblers have several options for feeding screws to fully or semiautomatic drivers, including screw presenters, bowl feeders and step feeders.
There’s nothing quite like a multistation automated assembly system. Watching robots, actuators and indexers go about their carefully choreographed routines with little or no human intervention can seem nothing short of miraculous.
The Boeing 777 jetliner is the backbone of many international airlines. The reliable workhorse, which has been used on long-haul flights for three decades, is produced in several variants. The aircraft’s 20-foot-wide aluminum fuselages range anywhere from 209 to 242 feet long.
