Welcome to the Surface Roughness Analysis Blog
Why do brakes squeak? When will a gasket leak? What caused the haziness in my painted finish?
Surface texture and function are tightly linked. Understanding the relationship between texture and function, and sharing that information with engineers and quality professionals, is what Michigan Metrology is all about.
The articles in this blog explore the concepts of surface texture analysis and measurement. We show how you can apply these concepts to solve problems related to leaks, squeaks, appearance, wear, noise, fit, friction, vibration, adhesion, and many other functions.
Looking for more information on specific surface texture parameters? Visit our Surface Texture Parameters Glossary for an introduction to dozens of 3D surface roughness analysis parameters.
And, if you want to learn much more about surface texture consider attending our online and in-person classes for an immersive introduction to the many concepts in surface analysis.
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
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
When measuring roughness with a stylus-based system you’ll hear the terms “traversing length,” “evaluation length” and “sampling length.” It’s important to understand their specific meanings and to adhere to them
…Modern metrology instruments, methods and surface texture parameters have made it possible to describe, in great detail, the functionally important features of a surface’s texture. A key aspect of surface
