Michigan Metrology offers training workshops and online classes in all aspects of surface texture and tribology. Dr. Don Cohen, one of the country's foremost experts in surface roughness, leads regular, two-day Surface Texture and Tribology short courses. The workshops focus on surface texture analysis, and how texture relates to component function, and on the basics of wear, friction and lubrication. The training is designed for scientists, engineers and technicians working in the fields of automotive, aerospace, materials, polymers, and others.
Dr. Donald Cohen distills his 30 years of experience in surface measurement and analysis into these compelling and easy-to-understand presentation.
The class material covers the following related topics:
• Intro to surface texture …why is it important?
• Instruments for surface roughness measurement (stylus, optical, AFM…)
• Filtering of surface texture measurements (2RC, Gaussian…)
• Parameters for surface texture analysis (Sa, Spk, Ssc, etc.)
• Wear (scoring, scuffing, galling, wear volume, wear depth…)
• Friction (how does surface texture relate to friction?)
• Sealing (gaskets, O-rings, lip seals, piston rings…)
• Surface energy/surface texture
• Correlation between non-contact and contacting systems
• Data analysis (T-Test, F-Test, principle components, regression…)
• Specifying surface texture (symbology)
• “Surface Metrology Strategy” (project approach).
All presentation material are provided to the attendees via email prior to the class. Depending on the time and interest, certain presentation modules may be eliminated or substituted.
We are now offering three online options for the Surface Roughness, Texture and Tribology class to make this fundamental training easier than ever to access. All versions of the course focus on surface texture analysis and how it relates to component functionality, as well as covering the fundamentals of friction, wear and lubrication.
Option 1 – Learn at your own pace at Udemy.com
This 4-hour version of the class at udemy.com provides a broad introduction to texture-roughness and tribology, in a series of modules that you can download and watch at your own pace. The class material is designed for anyone working in the fields of automotive, medical devices, aerospace, materials, polymers, and others. Engineers, technicians, quality professionals and students will all benefit from the broad range of topics and many excellent examples.
The complete Udemy course is now available on udemy.com for $49.95. It's an extremely affordable way to learn the fundamentals of surface roughness and friction.
Option 2 – Access the full class live online, March 10–11, 2021
For a deeper dive into texture/roughness and tribology we are offering a 2-day class online. Dr. Cohen will be teaching the course live online, via Webex, in a professional learning environment.
This version of the class goes into far greater detail regarding basic and advanced surface analysis and friction. In addition, you'll have full access for real-time questions and answers about how the material applies to your particular application. If you are an engineer, technicians or quality professional you will benefit from the in-depth coverage and pertinent examples this course offers.
The online format saves our attendees the cost of travel and accommodations typically associated with a course of this caliber. The cost to attend the two-day online class is only $950, with all class material provided prior to the course dates via email.
The two-day class will be held 8:30am–430pm EST on March 10 and 11.
Option 3 – Custom class for your company
Dr. Cohen also provides this course material as an online class customized for individual companies. These classes can be tailored to your company's specific needs and interests and can be presented through your internal systems.
It's a highly cost-effective way to train your team in critical surface texture-roughnes-tribology that is focused on your particular needs.
Wondering whether these courses are right for you? Here are some example segments from previous year's classes.
Dry Friction Module - This section covers the fundamentals of friction, real area of contact, and the relationship between surface texture and friction.
Filtering Module - Learn how to filter surface texture data and set cutoffs to highlight features within the texture.
About the Instructor
In 1994, Dr. Cohen established Michigan Metrology to help engineers and scientists solve problems related to “Squeaks, leaks, friction, wear, appearance, adhesion and other issues”, using 3D Surface MicroTexture Measurement and Analysis.
Dr. Cohen is a past Chairman of the STLE-Detroit section and has been active with the ASME B46.1 committee on surface texture since 1988, having served as Chair from 2005-2011. Dr. Cohen is also a Subject Matter Expert for the ISO surface metrology activities.
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. Early in his career, Dr. Cohen worked with IBM on optical disk drive development. He later joined WYKO Corporation as Product Manger and later became Vice President, leading the development of 3D surface texture metrology instrumentation.
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. Typically once a year the class is offered to a general audience in the Livonia, MI area.
