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

May 3–5, 2023, in Livonia, Michigan

Published: Thursday, December 15, 2022 - 13:00

(Michigan Metrology: Livonia, MI) -- Registration is now open for the Roughness, Texture, and Tribology class and workshop, which will be held in Livonia, Michigan, May 3–5, 2023. This class offers a unique opportunity to learn the fundamentals of surface roughness, friction, and wear, as well as the application of surface texture analysis in industry and research.

“This class is intended to help students to use surface roughness analysis in their workplaces,” says Don Cohen, Ph.D., who presents the course. “Live lectures and hands-on training with measurement equipment give our students a chance to ask questions and really learn what matters for their particular jobs.”

The class offers a deep dive into topics including:
• Measuring roughness and waviness
• Instruments for surface measurement
• Filtering texture data for the application
• Data analysis techniques and tools
• Surface texture parameters
• Specifying surface texture
• Applying surface texture analysis to wear, sealing, and other functionality
• Surface energy, adhesion, and texture, and paint appearance
• Mechanics of dry friction and rolling friction
• Fundamentals of lubrication
• Surface metrology strategy

The 2 1/2-day class will be presented live, in accordance with CDC guidelines to prevent the spread of the Covid-19 virus.

“We have been refining and expanding this class for nearly 20 years,” says Cohen. “It’s the most thorough and affordable opportunity we know to learn and apply the fundamentals of surface texture analysis.”

Class details and registration are available at michmet.com/classes. Registration requests can also be made by calling 1 (866) 953–5030 or emailing info@michmet.com.

About Donald Cohen

Donald 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, Cohen was vice president of engineering at WYKO Corp.—now part of Bruker Corp., 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 bachelor of science and master of science degrees in physics and a Ph.D. in optical sciences.
