Online Surface Roughness, Texture, and Tribology Class Now Available as Both Full Course and Modules

Designed for technicians, engineers, students, and scientists working in fields where surface texture is important

Published: Wednesday, June 15, 2022 - 11:59

(Michigan Metrology: Livonia, MI) -- The Surface Roughness, Texture, and Tribology short course, a staple of surface roughness training for engineers and quality professionals for almost 20 years, is now available in its entirety on the udemy.com education site. The course, presented by Donald Cohen, Ph.D., is now offered as a single course with more than 11 hours of content, and as individual course modules that allow students to tailor the material for their particular needs.

“The online format is a highly affordable way to learn about surface texture and surface interactions,” says Cohen. “We’ve now made the entire course available for students who want to take a deep dive into this material. For students who may need to focus their learning time, or who want to explore particular areas of the field, the individual course modules are a very cost-effective option as well.”

The course material is designed for technicians, engineers, students, and scientists working in fields such as aerospace, automotive, materials, medical devices, and others where surface texture, friction, or wear play important roles. The 10 course modules range in length from 45 minutes to 2 hours, including material covering:
• Surface Finish: Introduction, Instruments and Correlation
• Filtering for Roughness, Waviness, and Form
• Surface Roughness Parameters
• Wear Mechanisms, Measurement, and Specification
• Dry, Sliding Friction
• Lubricated Friction
• Rolling Friction
• Surface Energy, Wetting, and Surface Roughness
• Seals, Sealing, and Surface Finish
• Coatings: Surface Roughness from Substrate to Topcoat.

“This course goes far beyond the equations and math of analyzing surface texture,” says Cohen. “We focus instead on how texture relates to how components function, relating it to friction, sealing, durability, noise, appearance, and so on.”

The Surface Roughness, Texture and Tribology course available online is also offered live and in-person several times per year, and as customized training for individual companies. Details on all class options are available at michmet.com/classes, by calling (866) 953-5030, or emailing info@michmet.com.

About the instructor, 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 a B.S. and M.S. in physics and a Ph.D. in optical sciences.

About Michigan Metrology, LLC

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.
