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…

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 Although this rule has mostly been replaced by the more scientific and standardized GR&R…

In 2018, the world agreed to redefine the kilogram. Instead of being pegged to the mass of a physical object in a vault in France, the kilogram is now defined by a few fundamental constants in nature.
This means researchers no longer have to worry about a physical object that can decay or change…

In this job, I get a lot of questions. In fact, I did some figuring the other day and estimated, conservatively, that we have probably answered at least 50,000 gauging questions over the past 35 years or so.
Some of these questions have been challenging. They’ve pushed me to learn more about my…

Artec 3D has begun working with Handicap International to manufacture custom prosthetic devices for beneficiaries in refugee camps and their host communities in Rwanda.
According to the United Nations, in Rwanda more than 51,000 people need prostheses. Many suffered loss of limbs during the 1994…

When it comes to aircraft, poorly documented dents can lead to more significant problems, potentially compromising structural integrity or performance. Dents can trap moisture and lead to corrosion. The stress they generate can initiate fatigue cracks. Their effects on the structure can also affect…
