In metal stamping, especially in critical automotive applications, sometimes it’s not enough simply to close the control loop. Traditional control algorithms rely on eliminating an error between what is happening—as indicated by feedback from system sensors—and what should happen. High-speed motion…

Preventive conservation plays an important role in preserving art and cultural assets. To preserve their condition for as long as possible, it’s essential to slow down and evaluate aging processes and other factors that alter materials. To do this, it’s necessary to gain a holistic understanding of…
National Physical Laboratory
Through their exceptional material properties, graphene and related 2D materials have the potential to disrupt technologies such as energy-storage devices, composites, and electronics. Depending on the material, these properties can include high electrical conductivity, high mechanical strength,…

Alignment with Laser (AW Laser), a South African company, specializes in alignment. Using API laser trackers to align machinery and equipment in a range of industries, AW Laser provides measurement services, especially for shipyards, aluminum plants, steel mills, paper manufacturers, and sugar…
Oak Ridge National Laboratory
Researchers at the U.S. Department of Energy’s (DOE) Oak Ridge National Laboratory (ORNL) have developed a machine learning-inspired software package that provides end-to-end image analysis of electron and scanning probe microscopy images.
Known as AtomAI, the package applies deep learning to…

Inspired by the human finger, MIT researchers have developed a robotic hand that uses high-resolution touch sensing to accurately identify an object after grasping it just one time.
Many robotic hands pack all their powerful sensors into the fingertips, so an object must be in full contact with…

In today’s global manufacturing markets, the need for accurate measurement has moved well beyond micrometers, gauges, and calipers. That’s why manufacturers are replacing manual metrology tools with fully automated systems. But what is automated metrology?
Automated metrology, sometimes called 3D…

People often use the terms maintenance and reliability interchangeably. However, they are two separate concepts. Although there is some overlap, their scope and focus are quite different.
Understanding those differences, as well as how each concept affects the other, is a necessary step for…
