Biography:
Professor Ehmann has received his B.S. and M.S., degrees in 1970 and 1974 respectively from the University of Belgrade, Yugoslavia and his Ph.D. degree from the University of Wisconsin-Madison in 1979, all in Mechanical Engineering. He has served as a Professor from 1990 – current, an Associate Professor from 1985 – 1990, both in the Department of Mechanical Engineering at Northwestern University, and as an Assistant Professor from 1981 – 1985 in the Department of Mechanical Engineering at the University of Wisconsin-Madison. He has also held positions as an Adjunct Professor of the Department of Mechanical and Industrial Engineering at the University of Illinois at Urbana/Champaign, a Distinguished Honorary Professor of the Department of Mechanical Engineering at IIT-Kanpur, India, a University Chair Professor of Chung Yuan Christian University, Chung Li, Taiwan and a Visiting Professor at the University of Belgrade. Dr. Ehmann’s main research interests are in the interrelated areas of machine tool structural and metal cutting processes and dynamics, computer control of machine tools and robots, accuracy control in machining, and micro/meso-scale manufacturing. He has published over 400 articles and supervised over 50 MS and 50 Ph.D. students. He has served as the Editor in Chief of the Elsevier/Society of Manufacturing Engineers (SME) Journal – Manufacturing Letters and of the Technical Editor of the American Society of Mechanical Engineers (ASME) Transactions: Journal of Manufacturing Science and Engineering, as the President of the North American Manufacturing Research Institution of SME (NAMRI/SME), as the Chair of the Manufacturing Engineering Division of ASME and as the director of the International Institution for Micromanufacturing (I2M2). In 2004 he was named the James N. and Nancy J. Farley Professor in Manufacturing and Entrepreneurship at Northwestern. He was awarded a Distinguished Visiting Fellowship by the Royal Academy of Engineering at Cardiff University, the SME Gold Medal, MED/ASME Outstanding Service Award, NAMRI/SME Outstanding Lifetime Service Award, ASME Blackall Machine Tool and Gage Award, the ASME Milton C. Shaw Manufacturing Research Medal, SME Education Award, Hideo Hanafusa Outstanding Investigator Award (ASME and the Institute of Systems, Control and Information Engineers (ISCIE) in Japan), and the ASME K. Ehmann Manufacturing Medal. Professor Ehmann is a Fellow of ASME, SME and of the International Society for Nanomanufacturing (ISNM).

Abstract:
The rapidly evolving miniaturization technologies are perceived by many as potentially key technologies of the future that will bring about completely different ways people and machines interact with the physical world. The miniaturization of devices in different fields is today demanding the production, assembly and testing of components with manufactured features spanning the nano- to meso-scales. These fields include optics, electronics, medicine, biotechnology, communications, and avionics to name a few. Functional and structural requirements demand the use of various difficult to process engineering materials including metals, ceramics, and composites. To meet these rapidly evolving needs, a new paradigm for manufacturing must emerge, rooted in the very technologies that it addresses, namely, the development of new processes and manufacturing machines that are specifically focused on meeting the imposed requirements. The current scientific basis and technologies are still limited in their ability to engineer and physically impart precisely controlled geometric features, functional surface textures and patterns, to control and manipulate part properties, etc. In the presentation emphasis will be placed on process and device development and associated theoretical advances on examples of micro-cutting, -forming, -laser and -additive processing for tribological, biomedical and energy-related applications.
