D3 Vibrations (D3V) started operations in January 2004 to apply proven cutting-edge technology to the metal-cutting community. D3V has successfully applied data-driven solutions from small shops to large corporations. We provide industrial standard solutions for Predictive Maintenance and Industrial Noise; however, our methods for tool chatter and process analysis are unique and state-of-the-art. 90% of our business is application on the factory floor, with 10% working on product development and in conjunction with research universities such as Duke, Florida, University of Michigan, and University of North Carolina-Charlotte.
Dr. David Dilley leads our dynamics and vibrations projects by applying the latest structural testing techniques for determining the source of system instability to pinpoint the solution. Dr. Dilley was a Sr. Manufacturing Engineer for 5 years at GM Powertrain before being awarded a Boeing Fellowship to research metal-cutting vibrations from 1999-2003. He has his BSME from the University of Missouri-Columbia, MS Engineering Management from RPI, and a MSME and D.Sc. from Washington University in St. Louis. Email: dilley@
Dr. David Stephenson leads our cutting mechanics projects, where he is a renowned expert in automotive component processing, cutting force mechanics, and FEA modeling techniques. Dr. Stephenson was a Manager - Math Based Modeling at GM Research and GM Powertrain for nearly 20 years, and also VP of Applications at 3rd Wave Systems. He has his BSME and MSME from MIT, and his Ph.D. from the University of Wisconsin-Madison. Dr. Stephenson is co-author of the book "Metal-Cutting Theory and Practice". Email: stephenson@
Mr. Michael Williams leads our project management and software development. Mr. Williams worked at Siemens Automotive, Cadillac Automotive Products, and Alliance Group Technologies. He has his BS in Computer Engineering from Purdue University. Email: williams@
