Discover ASME B46.1 Updates and its Impact on Measuring and Testing Surfaces

Sep 10, 2020

The latest edition of B46.1-2019 incorporates many updates, including changes and clarifications to definitions and surface parameters, providing you with the ability to properly measure the performance of different surface textures. Two key additions include new sections on surface characterization of additive manufactured parts and functional correlations of surface texture. A recorded webinar is now available on-demand to learn more about the new B46.1‒2019 edition.
 
The speakers in this webinar include Brian Renegar, Dr. Jason Fox, and Christopher A. Brown, PhD, FASME, who worked on the development of this latest edition. Through their extensive education and work experience, the webinar’s presenters touch on many different areas across a multitude of industries.
 
The webinar provides the opportunity to explore:
 
  • Updated definitions, figures and Rsm calculation with example cases
  • The unique geometric characteristics of additive manufactured parts
  • Identifying an additive manufactured product’s surface topography
  • Corr on-demand elating and discriminating between process and performance parameters
 
Brian Renegar is a Physical Scientist at the Physical Measurement Laboratory at the National Institute of Standards and Technology (NIST). Renegar has performed scanned probe and optical measurements and calibrations in the field of surface metrology for over 25 years and is actively involved in research of measurement methods for forensic ballistic identifications of firearms and toolmarks. Renegar currently serves as Chair of the American Society of Mechanical Engineers (ASME) B46 Committee on the Classification and Designation of Surface Qualities.
 
Brian is joined by Dr. Jason Fox, a mechanical engineer in the Engineering Laboratory at NIST and the project leader for the Additive Manufacturing Part Qualification (AMPQ) project. Jason is also the chair for the for the B46 Project Team, PT 53, on Surface Finish for Additive Manufacturing and holds a M.S. and Ph.D. in mechanical engineering from Carnegie Mellon University. At NIST, Jason has focused on measuring and understanding the surface topography of AM parts to aid inspection and qualification.
 
Christopher Brown is a Professor of Mechanical Engineering and the Founding Director of the Surface Metrology Lab at Worcester Polytechnic Institute (WPI). He earned his PhD at the University of Vermont, with a dissertation on chip formation during machining and has published over 150 papers across surface metrology, Suh’s Axiomatic Design, manufacturing and sports engineering. Chris holds multiple patents on characterizing surface textures and has developed algorithms and software for topographic analyses, used worldwide in science and engineering research.
