During 2012-2013, he was on leave serving as the Assistant Director for Advanced Manufacturing at the Office of Science and Technology Policy in the Executive Office of the President of the United States of America. In this position he had responsibility for engaging the Federal sector and the greater scientific community to identify possible areas for policy actions related to manufacturing. He was responsible for coordinating Federal advanced manufacturing R&D, addressing issues related to technology commercialization, identifying gaps in current Federal R&D in advanced manufacturing, and developing strategies to address these gaps. Professor Kurfess \ has served as a special consultant of the United Nations to the Government of Malaysia in the area of applied mechatronics and manufacturing, and as a participating guest at the Lawrence Livermore National Laboratory in their Precision Engineering Program. He currently serves on the Board of Directors for the Society of Manufacturing Engineers, and the National Center for Manufacturing Sciences. His research focuses on the design and development of advanced systems targeting the automotive sector (OEM and supplier) including vehicle and production systems. He has significant experience in high precision manufacturing and metrology systems. He has received numerous awards including a National Science Foundation (NSF) Young Investigator Award, an NSF Presidential Faculty Fellowship Award, the ASME Pi Tau Sigma Award, SME Young Manufacturing Engineer of the Year Award, the ASME Blackall Machine Tool and Gage Award, the ASME Gustus L. Larson Award, an ASME Swanson Federal Award, and the SME Education Award. He is a Fellow of the AAAS, the SME and the ASME.

 

How do you know you’re getting the measurements you need? Depending on what you’re measuring and the technology you’re using, you may be getting what you expect or something completely different. With a focus on highly precise small to micro measurements, this workshop will help you use what you have better and to understand if another system might be better for your needs. Topics covered will include:

  • Feature-based metrology
    • Least squares fit
    • Minimum/maximum
    • CAD model comparison
  • Dimensional metrology—both rigid and flexible components/devices
  • Surface finish
  • Uncertainty
  • Data analysis
  • Comparisons of when to use which technology

Technologies covered will include

  • CMMs
  • Non-contact systems
    • CT scanning
    • Laser coupled with vision
    • SEM
    • AFM
    • Confocal microscopy
    • White light interferometry
    • Video metrology

Speakers include:

 

 

8:00 a.m. – 11:30 a.m.

Introduction to Lithographic Micromachining
WORKSHOP LEADER: James Marti, Associate Program Director and External Affairs Coordinator, Nanofabrication Center, University of Minnesota


James Marti is Associate Program Director and External Affairs Coordinator for the Nanofabrication Center. Prior to joining the NFC, Dr. Marti conducted research on atmospheric nanoparticles for academic and government labs, and served as R&D director for several small companies with a nanotechnology product focus. A physicist by training, his primary scientific interest has been the physics and chemistry of micron- and nanometer-scale particles, particle systems, and related materials.

Micromachining uses the tools and materials of the microelectronics industry to fabricate parts with features as small as a micrometer, 25 times smaller than the limit with conventional techniques. The tools of micromachining allow designers of medical devices, precision mechanisms, and other devices an unparalleled ability to fabricate very small structures. This short course will present an introduction to surface and bulk micromachining, simple MEMS structures, and photolithography. After a brief summary of techniques in the classroom, participants will enter the clean room to see the steps involved with fabricating and testing simple microstructures in the lab.

 

8:00 a.m. – 4:00 p.m.

MicroManufacturing Fundamentals
WORKSHOP LEADER: J. Rhett Mayor, Assistant Professor, Georgia Institute of Technology

 

J.Rhett Mayor is an assistant professor at the Georgia Institute of Technology. He holds a BScEng, MScEng, and a PhD from the University of Natal. Before joining Georgia Tech, he was President and CEO of Powerix Technologies and an Assistant Research Scientist with the S.M. Wu Manufacturing Research Center at the University of Michigan. His primary research interests are in micromanufacturing and micro-power generation with a focus on the development of enabling technologies through the application of integrated mechatronics design principles. His research has been sponsored by the National Science Foundation, NIST (ATP program), DARPA DSO, Department of Energy, and various industrial partners, including GM and Chrysler. Mayor has been an advisor for SME’s MicroManufacturing Conference since the inaugural event in 2003 and in 2009 was awarded the SME John G. Bollinger Outstanding Young Manufacturing Engineer Award.
