Measurement

NVision Inc., in cooperation with the Nasher Sculpture Center in Dallas, is making it possible for those with vision-impairment to interactively engage with some of the great works by modern sculptors. NVision, a leader in 3D noncontact optical scanning/measurement for more than 29 years, recently scanned several sculptures by Auguste Rodin (perhaps best-known for his sculpture, The Thinker) and Julio González for the Nasher. The scanning data was used to 3D-print to-scale replicas of the sculptures for a tactile educational experience for the blind and visually impaired.

The National Institute for Metalworking Skills (NIMS) and the Oregon Manufacturing Innovation Center – Research & Development (OMIC R&D) have united to define a set of Metrology standards and to develop a metrology certification process. Metrology, the study of measurement, has far-reaching applications in the manufacturing industry. The ability to compare and verify a physical part against its CAD model is in high demand, and that demand is predicted to increase.

G.H. Tool & Mold has expanded its capacity and capability by adding a second GOM ATOS Triple Scan high-resolution, 3D optical digitizer for automated measuring and inspection of its casting dies.

Contract inspection and reverse engineering capacity has doubled in terms of throughput, while the size of the component that can be measured has increased more than five-fold at Laser Scanning Ltd., based in Chapeltown, U.K., near Sheffield. It follows the installation of a second, larger coordinate measuring machine built by LK Metrology Ltd. at its Castle Donington, England, factory.

Swift work by NVision Inc. helped a major U.S. airline quickly repair a bird-damaged Boeing 737 wing and return the restored jet back to flight in just two days. The rapid turnaround helped the airline avoid the financial losses typically incurred by grounding aircraft.

The ability to “see through” a solid object was once thought to be a tool of the future, or a power belonging to Superman–but the technology is here today, and more widespread and accessible than you may have thought. Until recently, the technology of CT imaging was only available for use in medical settings. Over the last several years, it has found a new home in the world of manufacturing, and is opening up myriad opportunities never before available.

All machining operations have inherent variation caused by machine positioning errors, material variances, fixturing, tooling load and thermal changes. Many companies employ metrology at the end of machining to ensure that good parts go out the door, but it does little to improve manufacturing efficiency. Applying metrology before and during machining processes keeps operations in tight control, significantly improving process yield and final part quality at a much lower cost of production.

My latest trip took me to Las Vegas, where I attended HxGN LIVE 2019. Hosted by Sweden-headquartered Hexagon AB, the ninth biennial conference took place June 11-14 at the Sands Expo & Convention Center adjacent to The Venetian and The Palazzo resorts, and I participated in the Hexagon Manufacturing Intelligence division’s media program.
