Welding is said to be more art than science. In part, this is a nod to the vital, skilled work that welders perform. It’s also recognition of the fact that the physics of the process is really, really difficult to understand.
I joined a NIST project on laser welding about two years ago. Before…

Who can be against apple pie, motherhood, or good measurements? This is why everyone stands up and salutes when we are told to maintain our measurement systems in good calibration. But what is good calibration? By what method will we achieve it? And how will we know when we have it?
One day I…

Until recently, if a company wanted the best measurements in the world for the physical dimensions of one of its dimensional standards, it had to book time on the NIST Physical Measurement Laboratory’s (PML) Moore M48 coordinate measuring machine (CMM). Operating at NIST since 2000, this CMM—…

This year, 2016, marks the 100th anniversary of the founding of the U.S. Metric Association (USMA). Our mission is to help the United States complete its transition to the metric system. Although we’ve always expected that the adoption of the metric system here was just around the corner, all…
Electronic temperature compensation has been successfully applied to shop-floor gauges for more than 25 years. It’s become a mature technology and proven to be one of the most easily cost-justified means to achieve gauge correlation and eliminate the most common cause of high-resolution gauge…

Picture this: Your coordinate measuring machine (CMM) has crashed for the umpteenth time, and now it’s out of commission because you need to replace the probe head. Does this sound familiar? Across the world, manufacturers are facing the same problem: A situation occurs, you have to call the CMM’s…

If you’ve ever used a device that picks up signals over the air, you know that sometimes you just can’t get the signal to come in clearly. You point the device every which way, move it all around the room, do a little dance, but nothing seems to work. There doesn’t seem to be any explanation.…

After it’s all over, your lights will be just as bright, and your refrigerator just as cold. But very soon the ampere—the base unit in the International System of Units (SI) for electrical current—will take on an entirely new identity. In 2018, the SI base units are scheduled to be re-defined in…

NIST scientists have devised and modeled a unique optical method of sorting microscopic and nanoscopic particles by size, with a resolution as fine as 1 nm for particles of similar composition.
A stream of particles of various sizes enters the system at a single point, but the particles exit the…
