To reduce weight and fuel consumption, the aerospace industry increasingly relies on lightweight materials and new material combinations. That’s why the entire fuselage of the Airbus A350 XWB consists of carbon fiber composite (CFC) materials. In total, the long-haul aircraft reaches a CFC portion…
In aerospace vehicle manufacturing and assembly, including that at Northrop Grumman Aerospace Systems, measurements of composite part thickness are required for ensuring that underlying processes are within tolerance, and for achieving outer-mold line-control surface requirements.

E xtreme Fab Inc. is a structural metal fabrication company that has the tools and skills to build the massive machinery that the oil and gas, power, energy, and trucking industries require. One of their key customers is GE Aero Energy, a company that gives businesses and communities around the…
Large-volume metrology measurements are conducted at every major phase of alignment and integration of the Integrated Science Instrument Module (ISIM), which forms the main payload of the James Webb Space Telescope (JWST) at NASA Goddard Space Flight Center (GSFC). Both ambient and cryogenic…
Earlier this spring, thousands of people from all over the nation gathered in Springfield, IL, to honor the life of our beloved President Abraham Lincoln. After his death in 1865, his body was carried hundreds of miles by a funeral train. It passed through more than a hundred cities, with formal…

In the manufacturing industry, it is ideal to ensure high manufacturing accuracy without the need for inspection. In fact, however, the inspection and the measurement processes are performed for various reasons, such as to secure the product traceability, to visualize the quality of production,…
GE has introduced a metrology package for highly efficient, extremely precise 3D metrology performed with computed tomography (CT). The company states the enormous efficiency benefits, the use of industrial CT for nondestructive failure and structure analysis, and 3D metrology (especially for…
The reconstruction of scenes from multiple images or video streams has become an essential component in many modern applications. Many fields, including robotics, surveillance, and virtual reality, employ systems to reconstruct a 3D representation of an environment in order to accomplish specific…

Finance professional Joe Fabiani never imagined his love of exotic cars would develop into a full-time career. It began when he searched for an improved exhaust for his Porsche 993 but was at a loss to find one that conformed to the specifications he had in mind. Frustration with OEM stock…
NASA
Thanks to NASA’s Kepler and Spitzer Space Telescopes, scientists have made the most precise measurement ever of the radius of a planet outside our solar system. The size of the exoplanet, dubbed Kepler-93b, is now known to an uncertainty of just 74 miles (119 km) on either side of the planetary…

What do you do when 20 ultra-rare violins from the 1730s show up in town, ready to be measured? Further, what exactly would you want to learn from these measurements? For many of us, the first thing that jumps to mind is, “Why do these particular instruments sound so much better than others of…

The Oasis of the Seas is the largest passenger ship in the world with a gross tonnage of 225,282 and room for more than 5,400 passengers. Not surprising, it creates a huge bow wave when sailing the seas and encounters waves of more than 60 ft when crossing the Atlantic Ocean.
When wave action…

The Certification Committee of the Coordinate Metrology Society (CMS) has been laser-locked on its target to deliver its first Level Two Certification, a device-specific performance assessment for users of portable coordinate measuring machines (CMMs). Those efforts will come to fruition at this…
Laser trackers and the software that controls them have revolutionized the way metrology data have been taken. With software and hardware advances have come new and better ways to take measurements. One of these advances in metrology software is the ability to measure the angle normal to a mirrored…
