Surface Metrology 2018

WPI Short Course and Workshop

Wednesday June 27th and Thursday June 28th

     Surfaces cover everything, and their topographies influence behavior and are influenced by manufacturing and use. Despite the importance of topographies, much is still not understood about how best to measure and analyze them.

This event is to learn about how to measure, characterize and analyze topographies in order to understand how they perform, and how they were created. It is intended for engineers, researchers, scientists, technicians, students, professors, and managers. It is for people who are working in product and process design, quality assurance, as well as in forensics and a variety of scientific applications, like archeology, anthropology, paleontology, geography, and art conservation.

The short course covers fundamental principles of surface metrology, including conventional and multiscale. Participants can apply to present their research and topographic challenges for discussion in the workshops. There may also be opportunities to make measurements and do analyses during the workshop with the exhibitors.

In addition there will be a discussion on an International Industrial-Academic Consortium for Surface Metrology with an initial Center at WPI.

      Brown earned his PhD at the University of Vermont in 1983 studying machining. He then spent four years in the Materials Department at the Swiss Federal Institute of Technology conducting research on metal surfaces and teaching. For two years he was a senior research engineer working on surfaces and on product and process development at Atlas Copco's European research center.

     Since the fall of 1989 Chris has been on the faculty at WPI. Chris has published over a hundred articles on machining, axiomatic design, sports engineering, and surface metrology. He has patents on a fractal method for characterizing surface roughness, an apparatus for friction testing, and on sports equipment. He also develops software for surface texture analysis. He teaches grad courses on axiomatic design of manufacturing processes, and on surface metrology, and undergraduate courses on manufacturing and on the technology of alpine skiing. He also consults, and teaches courses, for industry on axiomatic design and on surface metrology.

     Chris co-chaired the first two International Conferences on Surface Metrology (2009 and 2010) and the first two Seminars on Surface Metrology for the Americas (2011 and 2012) all at WPI. He is a past chair of ASME B46, Committee for Classification and Designation of Surfaces; and he is Director of WPI's Surface Metrology Laboratory, and was a founder and director of WPI’s Haas Center for CNC machining.
