Hone plates, or sharpening stones, are used to produce a fine edge on knives, scissors, and other tools. A kit of stones provides progressively finer grit sizes and spacings to

“Roughness” can mean a lot of things, but in surface texture analysis, it has a very specific meaning. In this short video we look at how 2D and 3D surface

If you rely on average roughness (Ra) to control your surfaces, check out this short animation. It shows that very different surfaces can all have the same Ra value…and Ra

If I need to push a long, heavy block, it seems like it should be easier if I stand the block up rather than laying it flat on its face…and

When you’re thinking about the most engineered surfaces in a car, you may think of cylinder bores, clutches, brakes, etc. But we’d like to put one more item on your

Cavitation is the formation of air bubbles in a fluid as it goes from high pressure to low pressure. The dissolved gas can grow into bubbles—and under certain conditions those

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

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

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
