Will C. Hall Family Professor of Engineering and Professor of Manufacturing Engineering
University of California, Berkeley
PhDME ’76, MSME ’73, BSME ’72
More than a quarter century ago, David A. Dornfeld was introduced to acoustic emissions and their manufacturing applications while he attended graduate school in the College of Engineering. Now, Dornfeld, a manufacturing engineering professor at the University of California, Berkeley, is a leader in novel sensors for manufacturing processing.
Dornfeld’s research in acoustic emissions provides manufacturers with viable alternatives in advanced sensor techniques. Novel sensors have applications in traditional and precision manufacturing because of the very high frequency generated by fundamental mechanisms in manufacturing processes. Acoustic emission sensors have a distinct advantage because of their high signal-to-noise ratio, allowing for more robust assessment of process operation resulting in technological advances for the industry. Recent applications are for planarization in semiconductor manufacturing.
In addition to his work in acoustic emissions, Dornfeld studies burr formation, the jagged edges that result when metals are cut. He directs an industrial consortium working to help manufacturers prevent the burrs from occurring.
Dornfeld’s experiences at the University of Wisconsin-Madison helped him develop his successful career, and taught him how to interact with others, mentor and keep an organization’s mission intact. He has applied these lessons many times over the course of his professional life and has gained much respect and admiration for his abilities as a researcher and an educator.
Dornfeld, the Will C. Hall Family Professor of Engineering at the University of California, Berkeley, is a Fellow in the American Society of Mechanical Engineers and the Society of Manufacturing Engineers/Robotics International. He is a member of the American and Japan Societies of Precision Engineering, the Acoustic Emission Working Group, the International Production Engineering Research Institute (CIRP) and the Materials Research Society.
Dornfeld and his wife, Barbara, enjoy hiking and traveling and are working to restore an old house in the gold country of California.
