The portable measuring arm, or portable arm coordinate measuring machine (CMM) has become an important quality control tool at many manufacturing companies. With the flexibility to be used nearly anywhere on a manufacturing floor, from in-process checks to large-scale assembly to…
Superconducting (SC) magnetic and SC radiofrequency (SRF) devices designed for use in particle accelerators present challenging alignment problems. These devices are assembled and aligned at room temperature but operate at 2 Kelvin (K) to 4 Kelvin (K), with thermal offsets being large relative to…

On World Metrology Day this Friday, May 20, I ask that you pause a minute when you look at the alarm clock in morning, and then again as you set the thermostat or look at the weather report. World Metrology Day celebrates a link that binds humanity—the bond of a common measurement that is…

Put your hands together. Now move them back and forth to rub them against each other. Feel that heat? That’s from friction. No matter if it’s between siblings or the gears of an engine, we usually think of friction as a bad thing, and often it is. Friction can cause things to heat up, wear down,…

When a team of researchers at the National Institute of Standards and Technology (NIST) Physical Measurement Laboratory (PML) first tested a new kind of pressure sensor two years ago, initial results showed it was faster and had higher resolution than the centuries-old mercury-based method for…

Recently on the Taking Measure blog, we asked Tara Lovestead, a recipient of the 2016 Presidential Early Career Award for Scientists and Engineers (PECASE), a few questions about her life and work. She was recognized for her extensive application of new methods to rapidly and inexpensively detect…

Every day, new technology creates smaller and smaller materials and components. In many industries these parts require high magnification, sometimes up to 1,000X, to see submicron features. This is accomplished using a compound or upright microscope, where the user can select the objective lens.…

Whether it’s budgeting season, or you’re preparing for the future, you need to make strategic decisions about where your allocations will go. As planning commences to replace your current coordinate measuring machine (CMM) or to add a new one, important business considerations such as prior-year…

Researchers at the National Institute of Standards and Technology (NIST) have developed the first widely useful standard for magnetic resonance imaging (MRI) of the breast, a method used to identify and monitor breast cancer.
The NIST instrument—a “phantom”—will help standardize MRIs of breast…

During the course of its 100-plus year history, the National Institute of Standards and Technology (NIST) has had some researchers and scientists known to be colorful characters who were also pioneers in their fields. For computer scientist Karen Olsen, one scientist who stands out was Ethel…

When engineers at Pratt & Whitney’s assembly operations in Middletown, Connecticut, set out to determine the final tolerances between a massive Airbus engine and its enclosing nacelle, they face the intersection of thousands of precisely designed dimensions.
Although most of…

Fly-fishing, one of my favorite hobbies, is a lot like process improvement. Here’s how: Fly-fishing seems very simple—you throw a line in the water and wait for dinner. Of course, it’s much more complicated than that because rainbow trout are clever; they won’t bite just anything.
You have to…

Sandia’s Engineering Sciences Center helped mark National Engineers Week with a contest, asking Sandians to complete the following sentence: “You know you’re an engineer when… .” The contest drew dozens of endings for the sentence, and Sandians voted on which they liked best.
Barbara Lewis won…

Happy belated Pi Day! No, not pie day, Pi Day, which was last week. Pi is that Greek character you’ve heard of but aren’t quite sure what the big deal is. Pi is the ratio of a circle’s circumference to its diameter. As yawn-inducing as that may sound, it’s an important ratio because pi is the same…

Medical implants and spacecraft can suddenly go dead, often for the same reason: cracks in ceramic capacitors, which are devices that store electric charge in electronic circuits. These cracks, at first harmless and often hidden, can start conducting electricity, depleting batteries or shorting…

As happened with most every metrologist I know, I fell into metrology (the science of measurement) quite by accident. My degree was in chemical engineering, and I was probing the world around me to see what kind of work was out there for someone with my skills and interests. I learned of an…

NIST scientists have devised and improved a prototype instrument the size of a loaf of bread that can substantially increase the accuracy of length measurements in commerce. Perhaps surprisingly, it does so by achieving the most accurate measure of the refractive index of air reported to date.

Like many of you, I venture out on Saturday mornings to get groceries and gas. Until my college years, I never thought much about whether or not I paid the right amount at the pump, if the supermarket scale was correct, or if packaged foods actually contained the amount of product stated on the…
