New Live Online Surface Roughness, Texture and Tribology Class, March 10–11, 2021

Michigan Metrology, experts in solving problems related to surface texture, wear, finish and friction, announce an online, 2-day class in surface texture, friction and wear. The class, which will be held online March 10–11, is part of a suite of online training options that the company has made available to further understanding of surface roughness concepts.

“The March class is designed for engineers, technicians and researchers working in automotive, aerospace, materials, medical devices, polymers, and other fields,” said Don Cohen, PhD, who will present the course. “The online format makes it possible for our viewers to continue to grow their understanding of how texture affects component function—even while we can’t easily travel to attend trainings in person.”

The 2-day class is presented live online via Webex in a professional learning environment. This class offers a deep dive into course topics including:

  • Measuring roughness and waviness
  • Surface measurement instruments
  • How to correctly set filters for texture measurements
  • Data analysis techniques and tools
  • Surface texture parameters
  • How to specify surface texture
  • How surface texture relates to wear, sealing, and other functionality
  • Surface energy, adhesion and texture, paint appearance
  • Mechanics of dry friction and rolling friction
  • Fundamentals of lubrication
  • Surface metrology strategy.

Students viewing the class have full access to the instructor for real-time questions about how the material applies to their particular applications.

In addition to this 2-day class, Michigan Metrology also offers online courses through the training site Udemy, and customized online courses for individual companies.

“We have been holding classes in surface metrology and tribology for over fifteen years,” said Dr. Cohen. “Our students report that the online format gives them excellent tools to understand these fundamental topics, at a pace that helps them retain the class information.”

About the Instructor, Dr. Donald Cohen

Dr. Cohen established Michigan Metrology In 1994 to help engineers and scientists solve problems related to, “squeaks, leaks, friction, wear, appearance, adhesion and other issues,” using 3D surface texture measurement and analysis.

Prior to forming Michigan Metrology, Dr. Cohen was V.P. of Engineering at  WYKO Corporation (now part of Bruker Corporation), developing surface metrology instrumentation. He served as Vice Chairman/Chairman of the ANSI/ASME B46.1 Surface Texture Standards committee from 2000-2011 and is past Chairman of the STLE-Detroit section. He holds a B.S. / M.S. in Physics and a Ph.D. in Optical Sciences. 


Since 1994 Michigan Metrology has been providing high-volume inspection services and solving problems related to surface roughness, wear, texture, finish, flatness and more. Using advanced 3D surface roughness measurement and analysis techniques, state-of-the-art equipment and expert understanding of 3D surface metrology, the company has helped thousands of clients with solutions for surface development, manufacturing process issues and product warranty concerns.
