3D Surface Roughness and Wear Measurement, Analysis and Inspection

Surface Roughness, Texture, and Tribology Classes

Are you interested in learning about surface texture, wear, friction, sealing, surface energy, paint appearance, and more?

Dr. Don Cohen, one of the country’s foremost experts in surface roughness, presents the Surface Roughness, Texture and Tribology short course, covering a broad range of topics on surface texture and its impact on functionality.

NEXT CLASS: MAY 8–9, 2024

Registration will open for the class later this year.

This course is designed for scientists, engineers, and technicians working in the fields of automotive, aerospace, materials, polymers, and others. No prior study is required.

“This was one of the best classes I have ever taken. It really helped me understand surface texture and simply it made me a better inspector. It helped me see the bigger picture. I guarantee you’re going to want to learn more.”

Agustin Guzmán, Inspector at SpaceX

Dr. Cohen presents the Surface Texture and Tribology typically once per year, live in person. The annual class includes two days of lectures on surface metrology, tribology, and related topics. The cost for the full course is $950 per person. Light breakfast and lunch will be provided.

“I Highly recommend this course!” – Ivan Yermolenko

The class covers the following topics:

• Intro to surface texture …why is it important?

• Instruments for surface roughness measurement (stylus, optical, AFM…)

• Filtering of surface texture measurements (2RC, Gaussian…)

• Parameters for surface texture analysis (Sa, Spk, Ssc, etc.)

• Wear (scoring, scuffing, galling, wear volume, wear depth…)

• Friction (how does surface texture relate to friction?)

• Sealing (gaskets, O-rings, lip seals, piston rings…)

• Surface energy/surface texture

• Correlation between non-contact and contacting systems

• Data analysis (T-Test, F-Test, principle components, regression…)

• Specifying surface texture (symbology)

• “Surface Metrology Strategy” (project approach).

All presentation material are provided via email (PDF) prior to the class. Depending on the time and interest, certain presentation modules may be eliminated or substituted. 

“It was not until I found your videos that so many unanswered questions were answered. The videos you created that teach surface texture and tribology have been a tremendous help!” — Michael Bower, Analytical Chemist

About Don Cohen, Instructor

For more than thirty years, Dr. Donald Cohen has been measuring 3D surface roughness and analyzing the result to solve problems related to “squeaks, leaks, friction, wear, appearance, adhesion, and other issues.” Dr. Cohen formed Michigan Metrology in 1994 to provide 3D Surface MicroTexture Measurement and Analysis, serving industries including automotive, aerospace, medical devices, materials, and many others.

Throughout his career, Dr. Cohen has worked to advance the understanding and application of surface texture analysis, through his involvement in standards committees, industry groups, and other activities. His annual classes, surface texture parameters glossary, and surface-related articles and videos have helped many quality and manufacturing professionals to understand the concepts of surface texture and friction, and to apply them in their work and research.

Dr. Cohen has developed this class over the past 20 years having presented the material at numerous client locations as part of his training and consulting activities. The class is offered to a general audience in the Livonia, MI area, typically once a year. 

Dr. Cohen has an undergraduate degree in Physics from the University of Michigan, Dearborn, and graduate degrees in Physics and Optical Sciences from the University of Arizona.
