Abstract

Mechanical micromachining has emerged as one of the leading micro-manufacturing techniques for creating three-dimensional micro-scale features on a wide range of materials. The main driver of the micro-manufacturing technology is the demand from medical devices, energy, military/defense, optics, aerospace, and consumer products industries for miniature parts with microscale features, including components of miniature motors and turbines, micro-satellites, implantable and in-vivo medical devices, minimally invasive surgery equipment, micro robots, miniature drone aircraft for reconnaissance missions, miniature molds and dies, and compact bio-fuel reactors. Micromachining utilizes micro-scale milling and drilling tools. Although micromachining is kinematically similar to its macro-scale counterpart, scaling effects bring significant changes to both practical and fundamental aspects of the process. The basic capability of micromachining in creating three-dimensional geometries on metals, polymers, and composites has already been demonstrated. The first part of this talk will give an overview of the range of projects at Ozdoganlar’s Multiscale Manufacturing and Dynamics Laboratory. The research in Ozdoganlar group is divided into four thrusts, including; (1) mechanics of micromachining, (2) dynamics of micromachining, (3) development and analysis of novel micro/nano-manufacturing processes, and (4) application-oriented projects on micro/nano manufacturing and vibrations of miniature devices (including MEMS systems). The second part of the talk will include recent developments and results on modeling, numerical solution, and experimentation of micro-tool dynamics; and on micromachining of crystalline (fcc) metals including crystallographic anisotropy, hardening, rate sensitivity, and lattice rotation effects.

Biography

Prof. Burak Ozdoganlar is an Associate Professor of Mechanical Engineering and Affiliated Faculty Materials Science and Engineering at Carnegie Mellon University. Ozdoganlar received M.S. degrees in Aerospace Engineering and Mechanical Engineering from Ohio State University. He then attended University of Michigan for his doctoral studies, and received his Ph.D. degree in Mechanical Engineering in 1999. For the following two years, Dr. Ozdoganlar served as a Post Doctoral Research Associate at the University of Illinois, Urbana-Champaign (with R.E. DeVor and S.G. Kapoor). Between October 2001 and January 2004, he worked as a Senior Member of Technical Staff at the Structural Dynamics Research organization of Sandia National Laboratories in Albuquerque, New Mexico. He joined Carnegie Mellon University in January 2004 as an Assistant Professor of Mechanical Engineering. In July 2008, he was promoted to Associate Professor. His background includes modeling and experimentation of manufacturing and machining processes and systems; stability and dynamics of machine tool systems; modal analysis and testing; and structural dynamics. His primary research interests include micro/nano-manufacturing processes and equipment. Currently, he is the chair of Manufacturing Equipment technical committee of ASME Manufacturing Engineering Division. He is a member of the Phi Kappa Phi and Sigma Xi honor societies, SME/NAMRI, ASME, and ASEE. He is a recipient of Society of Manufacturing Engineers 2007 Outstanding Young Manufacturing Engineer award, and 2006 NSF/CAREER award. He was invited to NAE’s Frontiers of Engineering conference in 2007, and recently appointed as the Russell V. Trader Career Faculty Fellow (eff. Nov 1, 2009) at Carnegie Mellon University.
