We all know what happens to a squeaky wheel, right? But just how loud does a wheel need to squeak before it’s squeak-worthy of replacement?
During my years of auto repair, one of the interesting tidbits I was hipped to was this: What human ears perceive as a squeak is actually a high-frequency…

Nondestructive testing (NDT), as the name implies, is a methodology used for examining the hidden internal structure, measuring the thickness, or characterizing the material of industrial parts without cutting or otherwise damaging them.
NDT offers important tools for ensuring both safety and…

Researchers at the National Institute of Standards and Technology (NIST) have demonstrated a laser-based imaging system that creates high-definition 3D maps of surfaces from as far away as 10.5 meters. The method may be useful in diverse fields, including precision machining and assembly, as well…

A critical aspect of managing processes is the ability to measure well. Confidence in the integrity of collected data is imperative to ensure that appropriate decisions are made about acceptable product and process changes. It is possible that products declared “out of specification” may be the…

In October 2001, an international team led by Lockheed Martin was awarded the contract to build the next-generation Joint Strike Fighter (JSF) aircraft, which resulted in the development of the F-35 Lightning. The requirements for the new aircraft were complex, demanding new heights of lethality…

Assuming there are still questions about the suitability of a gauge for a particular application after a gauge repeatability and reproducibility (GR&R) study, Measurement Systems Analysis, 4th Edition (MSA-4), published by AIAG in 2010, recommends using an additional study in the calibration…
NIST
At the new NIST Center for Automotive Lightweighting (NCAL), workloads are fraught with stress and strain—all to help the auto industry take a heavy load off future cars and light trucks.
To meet proposed federal fuel-efficiency standards—54.5 miles per gallon by 2025, or nearly double today’s…
NIST
Recent experiments have confirmed that a technique developed several years ago at the National Institute of Standards and Technology (NIST) can enable optical microscopes to measure the 3D shape of objects at nanometer-scale resolution—far below the normal resolution limit for optical microscopy (…

Crash-test dummies, yarn-spinning machines, and steel girders in bridges. What do they have in common? Look inside them all and you find transducers, devices that measure the forces that push, pull, weigh upon, and slam into them. But transducers also have something in common: Until recently, it…

'Pssst! Hey kid, ya wanna be a metrologist?"..."Uh, what's a metrologist?"... "Ya get paid to measure stuff."..."Sounds kinda boring." So it goes at colleges and universities all across the United States.
The fields of science, technology, engineering, and mathematics—collectively known as STEM—…
The use of optical 3D shape measurement devices are rapidly gaining importance, allowing the reconstruction of real 3D objects efficiently. The 3D shape and texture can be obtained from stereo images acquired with a freely moving camera. This approach measures the image displacement from the…

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…

“So what’s the weather gonna do today?” I am sure that we have all been asked that after answering the first question (about what we do for a living) with: “Metrology.”
Metrology or meteorology? Both are studies of a particular science but are two words that are easily mistaken or misinterpreted…
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…

Materials that are firmly bonded together with epoxy and other tough adhesives are ubiquitous in modern life—from crowns on teeth to modern composites used in construction. Yet it has proved remarkably difficult to study how these bonds fracture and fail, and how to make them more resistant to…
NIST
To support the fair sale of gaseous hydrogen as a vehicle fuel, researchers at the National Institute of Standards and Technology (NIST) have developed a prototype field test standard to test the accuracy of hydrogen fuel dispensers. Once the standard is field tested, it will serve as a model for…

For decades now, the measurement systems analysis (MSA) approach has been the predominant method for evaluating measurement systems capability. Although this method is widely considered to be an acceptable and comprehensive approach throughout most of the world, a growing number of specialized…

I started out my day with a quick chat with a colleague about a client project she is working on. It concerns calibration, and I could hear the tone of a righteous lecturer creeping into my voice.
After a very long career in quality, I realize there are certain subjects that really get my blood…

What happened to the good old show-me-the-money capitalistic down-and-dirty business I grew up with? Where’s the cutthroat competition? What happened to “we’re big, you’re not, we’re doing it our way” partnerships?
Something happened when I was wasn’t looking because business is all so touchy-…
Most of us, at one point or another, have been faced with making a decision to purchase a software application. Whether a simple application to manage your schedule or a more complex quality management software, the challenge is the same: How do you decide if a software application meets your…
Nikon Metrology Inc.
A microfocus computed tomography (CT) system from Nikon Metrology is being used by BorgWarner Poland to improve research and development of turbochargers for passenger cars, light trucks, and commercial vehicles. The high-power (450 kV) X-ray equipment is able to penetrate the dense materials used…

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…
