"Mechanical Micro-Manufacturing and its Applications"

Burak Ozdoganlar, Department of Mechanical Engineering, Carnegie Mellon University

Mechanical micromachining has emerged as one of the leading micro-manufacturing techniques for creating three-dimensional micro-scale features on a broad 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 provide an overview of research at Ozdoganlar’s Multiscale Manufacturing and Dynamics Laboratory. The research in Ozdoganlar group involves mechanics and dynamics of multi-scale machining processes; development and analysis of novel micro/nano-manufacturing processes; application-oriented projects on micro/nano manufacturing and on vibrations of miniature devices; and precision metrology. The second part of the talk will include recent developments and results on modeling, numerical solution, and experimentation on miniature machine-tool and micro-tool dynamics.

Dr. Burak Ozdoganlar is an Associate Professor in Mechanical Engineering, Biomedical Engineering, and Materials Science and Engineering at Carnegie Mellon University. Between 2009-2011, he was the Russell V. Trader Career Faculty Fellow at CMU. He received his M.S. in Aerospace Engineering (1993) and Mechanical Engineering from Ohio State University (1995), and Ph.D. (1999) in Mechanical Engineering from University of Michigan. For the following two years, he served as a Post Doctoral Research Associate at the University of Illinois, Urbana-Champaign. From 2001 to 2004, he worked as a Senior Member of the Technical Staff at Sandia National Laboratories. He joined Carnegie Mellon in 2004 as an Assistant Professor, and was promoted to the rank of Associate Professor in 2008. His background includes modeling and experimentation of manufacturing and machining processes and systems, specializing in multi-scale (macro/micro/nano-) manufacturing and its applications; modal analysis and testing; and structural dynamics. Currently, he is the president of International Institution of Micro Manufacturing (I2M2), and associate technical editor for ASME J. Manufacturing Science and Engineering and for SME J. Manufacturing Processes. He is a member of the Phi Kappa Phi and Sigma Xi honor societies, SME/NAMRI, ASME, and ASEE. He is a recipient of 2011 Blackall Machine Tool and Gage Award (ASME); SME 2007 Outstanding Young Manufacturing Engineer award; 2006 NSF/CAREER award; and 2008 NAMRI/SME Outstanding Paper award.
