Metrology
Right now, the U.S. and Germany have different approaches to defining, or realizing, as the researchers call it, the kilogram. Here, NIST researcher Darine Haddad looks on as German researcher Beatrice Rodiek places a sphere on NIST’s highly accurate weighing machine, known as the Kibble balance. The goal of the research is to get closer to the same definition using the different methods. Credit: B. Hayes/NIST
The need for long-range height measurements has been around since the principles of layout work became a fundamental requirement in machine shops.
The first step in the manufacturing process is to lay out a piece by transferring a design or pattern to a workpiece. This is…
Our solar system has fascinated mankind for thousands of years. Astronomical research is looking for answers to the big questions of human existence. How big is the universe? How did it come into being? Astronomers all over the world use telescopes to cast their gaze into space.

Compliance with industry regulations and standards is a fundamental part of medtech. Without proper medical device compliance, companies risk patient harm, litigation, and reputational damage.
Fortunately, compliance with medical device regulations and standards is not an…
W ith the rapid digital transformation of manufacturing, including technologies like cloud solutions, digital twins, next-generation devices, automation, and AI, the role of metrology is poised for a transformative evolution. What can we expect from new quality systems, and how is the metrology…
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…
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…
