How would you go about measuring these coins? In terms of value, the most precious would likely depend upon your age, and possibly the time left on your parking meter!

It’s a common intuition that smoother surface texture is “better” for rotating or sliding over another component. It seems natural that a smoother surface would wear less, have lower friction,

You may have heard the term “F-Operator” and wondered what it is, and how it’s used. As we mention often, surface texture consists of a spectrum of spatial wavelengths, ranging

Scientists and philosophers through the ages have struggled with the concepts of friction. Leonardo da Vinci studied many aspects of friction, bearings, etc. In one set of experiments, he tied

I just finished reading this great book that nicely covers many aspects of surface roughness and tribology. The author, Laurie Winkless, is a physicist who loves communicating about science and

May 2 will mark the birthday of Frank Philip Bowden who, along with David Tabor, laid the groundwork for much of our modern understanding of friction and lubrication. “Putting two

High-precision surface texture measurement systems are more widely available now than they were 10 or 15 years ago. Yet, purchasing such systems can still be difficult to justify for small

Ra (Roughness Average, or average roughness) is the average height of all measured points on a surface. Ra is the most widely used surface texture parameter. As we’ve mentioned elsewhere

Though an optical profiler and stylus measurement system are very different technologies, they do also have some similarities. If you are used to working with stylus-based measurement systems, you know

When we think of how to measure wear, the first thought might be to quantify how much material has been removed from a surface. We might look at a change
