The jet in pneumatic dimensional (or air) gauging is the mechanical part of the sensing probe—air plug gauge, air ring gauge, air caliper gauge—through which compressed air is directed onto the part under measurement.
In its simplest form, we have two jets working in tandem facing in opposite…

Welcome knowledge seeker! Do you feel dazzled and awed by the great potential of artificial intelligence (AI)? Perhaps hesitant or lost when terms like convolution, deep learning, or autoencoder are thrown around? Well, fear not, for you’ve come to just the right place. You don’t need to be a…

From small family-run companies to tech giants, the business world is changing at an unrelenting pace. Amid a constantly evolving economic landscape and sometimes dizzying technological advances, one thing remains constant: the need to maintain the highest level of quality.
Whether manufacturing a…

Managers are commonly fed a diet of report-card data. These data have usually been aggregated into summaries, averages, and totals to characterize the big picture. As useful as such summaries can be, they can also be an obstacle to an effective analysis. Here, we’ll learn how to avoid this obstacle…

Whether you’re a small machine shop or a large multimillion-dollar manufacturing giant, there’s no doubt you use dimensional gauges to maintain the standards for quality in your production.
The accuracy of these dimensional measuring instruments must be periodically checked to ensure that they’re…

Time: We all have a sense of it, an innate feel for it. We see it and use it every day. If you’re like me, the first thing you do in the morning is check the time on your phone to see if you need to get out of bed or if you can close your eyes and catch a few more z’s.
Once you’re up and moving,…

In today’s market, it seems like all 3D scanners have similar specifications, as if manufacturers look at their competitors’ data and use the same numbers. Data sheets, marketing videos, and even product appearances all look comparable, making it difficult to distinguish quality based on technical…

While clinical trials are the gold standard for generating clinical data to use as evidence of your medical device’s safety and effectiveness, they are by no means the only way to gather clinical evidence.
Real-world data (RWD), which typically come from routine healthcare delivery or…

Wilhelm Weber gets the distinction of having the unit of magnetic flux, the weber (Wb), named in his honor. Magnetic flux measures the total magnetic field that passes through a surface.
(Wondering how to pronounce weber? Hear all about it from one of our researchers.)
The amount of magnetic flux…

I once transformed my face to look like Ron Swanson—for science.
I never thought disguising myself with wigs and makeup would be part of my job, but as a NIST facial recognition researcher I sometimes do just that. To make myself look like the gruff character from the show Parks and Recreation, I…

Centurion Performance & Engines (CP&E) is an Illinois-based manufacturer of custom performance engines and parts. It’s also a custom tuning and install body shop in high demand.
Founded in 2009, the company has a research and development department equipped with advanced tools including a…

Nuclear fusion is seen as a possible visionary solution to the energy problems of the future—clean and comparatively low-risk. Small atomic nuclei are fused at extreme temperatures and pressures instead of being split as in the reactors of conventional nuclear power plants. A similar process takes…

Practically everything you use in your everyday life works because of measurement science. Without precise measurements, your car wouldn’t run, your phone wouldn’t work, hospitals couldn’t function, and the ATM would fail.
The National Institute of Standards and Technology (NIST) is the national…

Imagine how a phone call works. Your voice is converted into electronic signals, shifted up to higher frequencies, transmitted over long distances, and then shifted back down so it can be heard clearly on the other end. The process enabling this shifting of signal frequencies is called frequency…

Wire bonding is a key process in semiconductor production. Extremely fine wires with diameters of 15 to 75 µm are used to create tiny electrical connections between a semiconductor chip and other components. The distances between the bond wires are often less than 100 µm. Any deviation, however…

In 1988, a small company began developing and supplying electronic instruments that automatically compensate for temperature-induced errors in industrial gages that are used to make precision dimensional measurements. Its products are now in use worldwide, improving factories and workshops that…

The world keeps time with the ticks of atomic clocks, but a new type of clock under development—a nuclear clock—could revolutionize how we measure time and probe fundamental physics.
An international research team led by scientists at the Joint Institute for Laboratory Astrophysics (JILA), a…

It’s not easy making green.
Scientists have made small red and blue lasers for years, but other colors have been a challenge. Now, researchers have filled an important technology gap by creating orange, yellow, and green lasers tiny enough to fit on a chip. Low-noise, compact lasers in this…

Electronic temperature compensation in gaging has become a valuable tool in improving the accuracy and gage repeatability and reproducibility (GR&R) of gages in harsh manufacturing environments.
The need for temperature compensation comes into play when the expected errors from temperature…

Identifying one faulty turbine in a wind farm, which can involve looking at hundreds of signals and millions of data points, is akin to finding a needle in a haystack.
Engineers often streamline this complex problem using deep-learning models that can detect anomalies in measurements taken…

We ended the previous gaging article talking about the 10:1 rule as it applies to the performance of a gage.
The rule says that the gage should perform to a level better than 10% of the tolerance. Although this rule has mostly been replaced by the more scientific and standardized GR&R…

Up-to-date and accurate maps of the waterways are a prerequisite for safe and efficient shipping in Germany. Authorities such as the Federal Maritime and Hydrographic Agency, but also private harbor operators, are obliged to provide these maps in an up-to-date form at all times. Primarily, the…
