Micro/Meso-Scale Manufacturing using Miniature Machine Tools (MMTs)
The interest in small components and small features has been rapidly increasing. Biotech, biomedical, optics, aerospace, military, defense, security, automotive, microelectronics packaging, and communication industries have been increasingly demanding miniature products and miniature features in larger products. This demand mainly arises from the potential advantages of miniaturization: multiple functionality; weight, space, and material savings; strategic placement/configuration availability; increased reliability; and other, currently non-existent capabilities. The development of complex micro devices necessitates efficient and economical creation of sophisticated mechanical structures with 3D geometrical features made from diverse selection of materials. Although the capability for making micro/meso-scale products exists, high cost and low throughput of the current technologies prevent efficient and economical production.

Prof. Ozdoganlar’s research focuses on processes and equipment for micro-manufacturing. Research projects include experimental, theoretical, and numerical (simulation) studies. The processes of interest include mechanical micromachining process, where micro-scale milling, drilling, and grinding tools as small as 10 µm in diameter are used within precision and miniature-machine-tool platforms. The research projects in his laboratory include fundamental understanding of the process mechanics (the effect of workpiece crystallography, modeling micromilling forces); micro-tool characteristics (micro-tool failure and wear, enhanced micro-tool fabrication); dynamic behavior of micromilling (analytical modeling of micro-endmill dynamics, dynamics of micromilling process); and applied projects on micromachining (fabrication of biomedical devices, micro-scale electrodes and molds, micromachinability of materials). Current research is aiming to create nano-scale (50 nm) structures using a new form of material removal.

Prof. Ozdoganlar is also interested in developing novel micro-scale solid freeform production processes for metals and polymers (with Profs. Anna and Weiss); the effect of thin-film microstructure in chemical-mechanical polishing (with Prof. Higgs, III); dynamic characterization of micro- and nano-scale structures (with Prof. Sitti); repetitive impact dynamics (with Prof. Wickert); and receptance coupling for dynamics of complex systems (with Prof. Schmitz of Florida).

Modeling, Simulation and Experimentation of MEMS/microsystems
Recent advances in Micro-electromechanical System (MEMS) fabrication and design techniques, including surface micro-machining and LIGA, have made it possible to create complex, multi-task integrated systems. However, current industrial applications of the microsystems are limited to various sensors, actuators, and mirror arrays. Realization of commercially viable microsystems products requires thorough understanding, and eventually prediction, of their performance and reliability characteristics. Prof. Ozdoganlar’s research includes modeling and experimental validation of structural dynamics and coupled-physics phenomena in MEMS. Nonlinear shock and vibration response of microstructures is being investigated. Specialized experimental equipment is being developed for dynamic testing of microsystems. Reliability and uncertainty quantification of MEMS are other areas of research.

Multiscale Manufacturing and Dynamics Laboratory
Ozdoganlar’s multiscale manufacturing and research laboratory includes experimental and computational equipment in support of the research projects. A miniature machine tool with two 160,000 rpm spindles and 10 nm resolution, instrument with a force dynamometer and a microscope is used for micromachining research. An instrumented microtome is used for in-depth investigations of mechanics. Another important equipment, acquired through an NSF/Major Research Instrumentation award, is a micro-capable, scanning laser Doppler vibrometer system with two lasers, strobe capability, and a microscope, allowing dynamic characterization of micro and nano-scale structures. An instrumented tissue-testing equipment is also included in the laboratory. General equipment includes oscilloscopes, data acquisition systems, amplifiers, and piezo actuators.
