New employees at the National Institute of Standards and Technology (NIST) are often surprised to learn that our agency is part of the U.S. Department of Commerce. How could this be? On the surface it seems that the missions of the two organizations couldn’t be more different. The Department of…

Buildings account for about 40 percent of U.S. energy consumption, and are responsible for one-third of global carbon dioxide emissions. Making buildings more energy-efficient is not only a cost-saving measure, but also a crucial climate-change mitigation strategy. Hence the rise of “smart”…

Recently, the team at 4C Creative Cad CAM Consultants in Emmen, Netherlands, was given a unique task: How to get a vintage Harley Davidson motorcycle back on the road again.
What was fun about this project wasn’t how challenging it was, or how much expertise it required. The joy was in the end…

NVision’s engineering services are helping managers of coal-fired power plants converting to natural gas to determine more quickly where to install updated instrumentation necessary to retrofit turbines to accommodate the new power source.
“By measuring the equipment via laser scanning, then…

Any number derived from real observation is made up of three components. The first of these is the intended signal, the “perfect” value from the object being observed. The second is error (or noise) caused by environmental disturbance and/or interference. The third is bias, a regular and consistent…
Lawrence Livermore National Laboratory
A team of Lawrence Livermore National Laboratory (LLNL) scientists has simulated the droplet-ejection process in an emerging metal 3D-printing technique called “liquid metal jetting” (LMJ), a critical aspect to the continued advancement of liquid metal printing technologies.
In their paper, which…

Before a fixture gauge is designed, the engineer must understand what specifications must be inspected. In many respects, the gauge’s design reflects not only the design of the part but also the manufacturing processes that produced it.
Machinists must establish datums in order to machine a part…

To establish a successful quality control program, you need good instrumentation, robust software, and trained users. But even with everything in place, there are some common pitfalls to watch for when using a spectrophotometer to analyze color quality.
1. Bad standards and samples

Metrology may sound like an esoteric dark art, but it isn’t. If you’re involved in manufacturing of any stripe, you’re almost certainly a metrology practitioner. Coordinate metrology, on the other hand, is a more narrow subset of the field but still widely used in many industries for various…

Founded in 1984, the Coordinate Metrology Society (CMS) has championed portable coordinate measuring machine (CMM) technology ever since its inception. In some ways, the focus on portable CMMs overshadowed the traditional fixed CMM in much the same way any new technology garners the lion's share of…
