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.
Why do some bearings look shiny with wear?April 25, 2023
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
Visualizing “filtering” — an animationApril 18, 2023
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
A plant with self-cleaning leaves?March 29, 2023
A lot of effort goes into creating materials that can resist sticking, repel water, or keep oils off of cell phone screens. But some plants are able to accomplish tasks
Paint Finish and Spatial WavelengthsMarch 14, 2023
Two lots of steel pass inspection for surface roughness. Yet, when we paint a panel from each lot, one looks great, and the other…does not. How can it be, when
How do I calibrate my fingernail?February 28, 2023
Tactile gages (comparator strips) can aid in quick assessment of a process, but they have limitations for process control. We look at their strengths and weaknesses in this blog post.

Curling again! Applying the lessons of micro-texture to the macro texture of curling iceJanuary 23, 2023
We’ve had a lot going on related to ice lately! It is that time of year… A few months ago, we posted an article about the sport of curling, which
Ice and friction – there’s a lot going on!January 19, 2023
Want to maximize your fun while skating? Make sure that the ice temperature is -7°C! For many years I thought that concentrated pressure is what melts the ice when you
When is “non-contact measurement” important?January 9, 2023
For surface roughness measurement, it would seem like “non-contact” methods would always be preferable. After all, being able to measure a surface with no possibility of contact damage would always
Seasons Greetings from Michigan MetrologyDecember 20, 2022
We wanted to take a moment to wish everyone a great season and happy new year. We’d like to express our gratitude for making it through all of the “peaks
