Registration is open for the Roughness, Texture, and Tribology class and workshop, which will be held in Livonia, Michigan, May 3–5. 2023. This live, in-person class offers a unique opportunity to learn

We tend to think of “new” surfaces as shiny and smooth, and “worn” surfaces as rough, dull, or uneven. But for a bearing surface, the opposite is often true: the

Surface texture can be described as a spectrum of spatial wavelengths. “Filtering” is the process to isolate the wavelengths that matter for our application. But what does that really look

Years ago, I’d just completed one of my first major surface roughness measurement projects, and I was considering my next steps to form an actual business. I thought that I

We’ve updated the Michigan Metrology website to give our visitors a better experience. All of the helpful content that you’ve come to expect is still here—the Surface Texture Parameters Glossary,

As you may know, our Surface Roughness, Texture and Tribology course has been available as ten individual modules for online learning at udemy.com. We have had quite a few requests

Most quality professionals working with surface texture/roughness are well familiar with “R” parameters, such as Ra (average roughness). These widely used parameters are derived from 2-dimensional measurements, typically generated by
