MINDING THE GAP: MOVING NEW MATERIALS TECHNOLOGY FROM THE LABORATORY TO THE FACTORY FLOOR
Dr. David Bowden
Boeing Research & Technology
In low-rate production environments, such as in rapid prototyping and much of today’s defense manufacturing, the time and cost of qualifying new materials and processes for service represents a barrier to innovation. The stringent requirements for extensive fabrication and testing necessary to ensure safety and performance result in long and expensive development programs that are unaffordable and cancel out any economic advantages offered by the new technology. Ironically, efficient manufacturing processes that seem most attractive in the low-rate production environment do not get used because the cost of qualifying the product of the process is prohibitive, with the result that we continually fall back on conventional approaches. In this presentation, the requirements for qualification of new aerospace materials will be reviewed, and innovative methods utilizing advanced modeling and simulation tools that streamline the qualification process and break down the barriers to innovation will be discussed. The innovative additive manufacturing process, electron beam direct manufacturing (EBDM) of metallic components, will be used to demonstrate development of the methodology. This work is sponsored by the Defense Advanced Research Projects Agency (DARPA) Defense Science Office.
Dr. David Bowden is a Technical Fellow with Boeing Research & Technology. His 32-year career at Boeing has spanned from the research laboratory to the shop floor. He has supported a variety of military aircraft programs, including the C-17, F-15, F-18, Joint Strike Fighter, National Aerospace Plane (NASP), and JASSM missile. Since joining BR&T, he has led over $25M in externally-funded research programs in advanced materials development for DARPA, AFRL, ONR, NAVAIR, and DOE customers. In 2005-06, he was the Yorkshire Forward Sponsored Chair in Manufacturing at the Advanced Manufacturing Research Centre at the University of Sheffield in the UK. He is currently the principal investigator for tiFAB, a part of DARPA’s Open Manufacturing Initiative, and serves as the Boeing technical focal for the American Lightweight Metals Manufacturing Innovation Institute (ALMMII), the newest addition to the National Network for Manufacturing Innovation (NNMI). He received his B. S. in Materials Science & Engineering from the University of Florida (1975), and M. S. in Metallurgy (1978) and Ph.D. in Chemical Engineering (1982) from the Georgia Institute of Technology. He is a Fellow of ASM, and a member of Georgia Tech’s Academy of Distinguished Engineering Alumni.
