Surface Roughness, Texture, and Tribology Short Course 2025
Looking for an opportunity to learning about surface roughness and how it relates to wear, friction, sealing, vibration, noise, appearance, and more?
Dr. Donald Cohen, one of the country's foremost experts, is once again presenting his Surface Texture and Tribology short course, May 7-8, 2025, in Livonia, Michigan. The course modules cover a broad range of topics on surface texture and how it impacts the functionality of a component.
This course is designed for scientists, engineers and technicians working in automotive, aerospace, materials, polymers, and other fields. The class offers material to benefit both relative novices and advanced metrology users to further their understanding of these essential topics.
Course material includes:
• Measuring roughness, waviness, and form
• Surface roughness parameters
• Wear Mechanisms, Measurement, and Specification
• Friction (Sliding, Rolling, Lubricated)
• Noise, Vibration, and Harshness
• Surface Energy, Wetting, and Adhesion
• Sealing
• Coating Appearance
• Surface Metrology Correlation, Specification and Strategy

Michigan Metrology Introduction
Переглядів 1002 місяці тому
Since 1994 Michigan Metrology has provided surface roughness, texture, and wear measurement, analysis and training. Using non-contact, 3D surface roughness measurement and analysis, we’ve helped thousands of clients solve issues related to squeaks, leaks, friction, wear, fit, finish, adhesion, noise, and vibration. In this short video Don Cohen, President of Michigan Metrology, describes our co...
how do we define average roughness
Переглядів 4,7 тис.Рік тому
Average Roughness-in surface texture measurement, it's one of the most frequently specified surface roughness parameters. In this video we look at how average roughness (Ra, or Sa) is calculated for 2D (profile) and 3D (areal) measurements. We look at what Ra can - and can't - tell us about a surface. And, we discuss the differences between Ra and Sa, and some similar parameters that you may en...
How Do We Define "Roughness?"
Переглядів 1,1 тис.Рік тому
"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 texture data can be filtered down to a band of spatial wavelengths that we can analyze as “surface roughness.” It’s a fundamental concept of surface texture analysis, and the basis for our upcoming videos on surface roughness measurement as...
Average Roughness (Ra) - Michigan Metrology Surface Measurement
Переглядів 336Рік тому
Are you relying on average roughness (Ra) to control your surfaces? We made this short animation to show that very different surfaces can all have the same Ra value...and that Ra alone can't tell you which one you've manufactured! Michigan Metrology provides 3D, non-contact inspection services and uses advanced surface roughness measurement to help solve problems related to wear, texture, finis...
How Rough is Roughness?
Переглядів 163Рік тому
We know that measuring surface roughness is important for performance, quality, and durability. But how "rough" are the typical "average roughness" values that we see on prints and specifications? In this video we put roughness values to some common automobile components to make it a little easier to visualize, say, a 2 micron Ra surface texture. Want to know more about average roughness? Check...
Friction and the Real Area of Contact
Переглядів 1,3 тис.Рік тому
Friction and surface texture - If I need to move a heavy block, it seems like it should be easier if I stand the block up rather than laying it flat on its face...and yet, as Leonardo Da Vinci observed, the size of the contact area doesn't seem to affect friction. The reason why lies in the difference between the Real Area of Contact and the Apparent Area of Contact. In this video we zoom in on...

Surface Texture Filtering - Surface Roughness Filtering
Переглядів 939Рік тому
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 like? One way to visualize it is to think of sorting different sized stones. The size of the stones is analogous to the size of the surface features. In this short animation we show how we can use that analog...
Surface Texture - Why the spatial wavelengths are important for paint
Переглядів 211Рік тому
Two lots of steel both pass inspection for surface roughness. Yet, when panels made each lot are painted, one looks great, and the other…does not. How can this be, when the roughness was the same? The answer is in the surface texture spatial wavelengths. Surface texture consists of a spectrum of spatial wavelengths. We define what we consider "roughness" with cutoffs, based on the application. ...
