Many times per week we’re asked, “Is X-ray or CT the correct inspection method for my project?” The answer, of course, isn’t always straightforward. This article will highlight some strengths and weaknesses of each method.
The subject for inspection is a carbon fiber board with inclusions…

This article will focus on a sampling method that is commonly used to analyze fluid: direct liquid filtration. Simply put, direct liquid filtration is a sampling technique used to determine the particles present in a liquid.
In direct liquid filtration, the liquid with suspended particles is…

Rising costs from inflation and increased focus on reducing carbon dioxide emissions make product loss management more important than ever in dairy plants. One major reason these losses occur is because timings or other process parameters are set incorrectly, causing a lot of valuable dairy product…

Detailed virtual copies of physical objects, called digital twins, are opening doors for better products across automotive, healthcare, aerospace, and other industries. According to a new study, cybersecurity may also fit neatly into the digital twin portfolio.
As more robots and other…

In a highly regulated industry like medical technology, manufacturing processes must undergo either process verification or process validation to ensure they’re consistently producing the correct result. The question is, which one should you use?
Verification and validation are two different…

It’s been decades since air gauging came into existence, and many changes and refinements have been made over the years. It has proved itself as a reliable and accurate method of gauging parts, particularly in cases of close tolerances and fine finishes. Its high accuracy, simplicity, and…

In a brightly lit subterranean lab at the National Institute of Standards and Technology (NIST) sits a room-sized electromechanical machine called the NIST-4 Kibble balance.
The instrument can already measure the mass of objects of roughly 1 kilogram, about as heavy as a quart of milk, as…

When deep-learning models are deployed in the real world—perhaps to detect financial fraud from credit card activity or identify cancer in medical images—they are often able to outperform humans.
But what exactly are these deep-learning models learning? Does a model trained to spot skin cancer in…

When I started working from home in 1998, it wasn’t by choice. I was writing for a major record label that decided—in so many words—that I was like a painting that didn’t go with the furniture. (Fine. Know what you get when you play New Age music backward? New Age music.)
My panic-stricken…

The worldwide pandemic presented unique challenges for every manufacturer in the United States. Hexagon’s Manufacturing Intelligence division was no exception. While its factory operations team has always pursued continuous improvement, the disruptions and slowdown related to the pandemic offered a…

As 2022 draws to a close, we ask NIST’s senior researchers to look ahead to the new year and beyond. They research topics that affect all of us, from indoor air quality to cybersecurity. So we ask our fellows, “How will the technology you are working on today affect society in the years to come?”…

Quality assurance and quality control (QA/QC) are a continual part of any manufacturing process. No matter how many times your factory has executed the same procedure, you must regularly perform quality checks to maintain the same quality level of your process. Quality control on a manufacturing…

The demand for printed circuit boards (PCBs) will only increase until a superior technology comes of age. The global market for PCBs could rise to $72.3 billion by 2026. PCBs have become essential everywhere, from infrastructure to consumer products.
The overwhelming demand for PCBs for the…

An important part of production is to carefully monitor and control temperature, speed, volume, weight, or mass. To ensure these measurements are always accurate, manufacturers need to calibrate their equipment and instruments regularly.
Devising a proper equipment calibration schedule can be a…

Terahertz radiation, with wavelengths that lie between those of microwaves and visible light, can penetrate many nonmetallic materials and detect signatures of certain molecules.
These handy qualities could lend themselves to a wide array of applications, including airport security scanning,…

Metallized substrates such as two-piece metal packaging are expensive to produce, and they make print color-control challenging. Although many in the metal decorating sector are hesitant to embrace color measurement, it’s the fastest, most accurate, and cost-effective way to produce consistent…

When looking in the fridge, you notice a package of minced meat sitting at the back of one of the shelves, totally forgotten. A check of the best-before date reveals it had expired two days earlier. Like so many consumers, you feel an internal struggle emerging: risk food poisoning or discard a…

Many trade shows have disappeared or diminished in recent decades—but not the International Manufacturing Technology Show, a biannual event held every even-numbered year in Chicago, this year from Sept. 12–17. In its 33rd year, IMTS was of sufficient scope to take up nearly half of McCormick Place—…

I am 100 percent a millennial (lol), which—according to the Merriam-Webster dictionary—means I’m a “person born in the 1980s or 1990s.” To me, being a millennial means belonging to a cultlike group within a large population of present-day wannabe-adults for whom seemingly arbitrary words like…
