In-Person Surface Roughness, Texture, and Tribology Class/Workshop

Livonia, Michigan, May 4–6, 2022

Published: Wednesday, February 16, 2022 - 12:59

(Michigan Metrology: Livonia, MI) -- A live, in-person, two and one-half-day class and workshop in surface texture, friction, and wear will be held in Livonia, Michigan, on May 4–6, 2022. The class will include both lectures and hands-on equipment demonstrations, to help students expand their understanding of surface roughness concepts and applications.

“The May 2022 class is designed for engineers, technicians, and researchers working in automotive, aerospace, materials, medical devices, polymers, and other fields,” says Don Cohen, who will present the course. “It’s been over two years since we have been able to present this class in person. The live format can be more engaging, and it enables immediate question-and-answer feedback. The additional workshop component will give attendees a chance to get hands-on training with measurement equipment such as optical profilers, tribology testers, and 3D scanners.”

The class will offer 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

“We have been holding classes in surface metrology and tribology for over fifteen years,” said Dr. Cohen. “Our students report that the in-person format helps them to focus, understand and retain this fundamental information.”

Registration requests can be made by emailing info@michmet.com. More class details are available at michmet.com/classes.  

About the instructor, Donald Cohen

Donald Cohen, Ph.D., 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, Cohen was VP of engineering at WYKO Corp. (now part of Bruker Corp.), where he developed surface metrology instrumentation. He served as vice chairman and 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. and M.S. in Physics and a Ph.D. in optical sciences.

About Michigan Metrology

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.
