Part 1 – Introduction, Instruments & Filtering
August 27, 2026, 1:00 PM EST. Register now!
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, is presenting excerpts from the popular Surface Roughness, Texture, and Tribology course. The series of free, one-hour webinars will give an excellent introduction to surface texture how it impacts a part’s function.
The webinars are designed for engineers, quality pros, technicians, and students who are looking to expand their knowledge of surface texture. No prior study is required.
The Part 1 Webinar will cover:
- Introduction to surface texture
- Instruments for surface roughness measurement
- Filtering (roughness vs. waviness vs form, cutoffs, etc.)
Part 1 serves as a foundation for the rest of the series, so we highly recommend starting here!
A video of this webinar will be available for attendees, after the live recording date.
Upcoming webinar segments:
- Surface Texture Parameters (September)
- Wear Measurement (October)
- Dry Friction (November)
- Lubricated Friction (December)
- Surface Energy, Surface Wetting, and Surface Texture (January)
Looking to dive deeper?
Dr. Cohen’s full Surface Roughness, Texture & Tribology course is a 2-day, deep dive into surface roughness and applications for controlling friction, wear, sealing, fit, finish, coating appearance, and many other topics. It’s a fantastic way to immerse yourself in surface texture and to learn how it applies to your work or research.

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.
