Mould & Die CAD/CAE/CAM, Material processing from micro to macro scale, Tribology, Equipment design and optimization
Dr. Yun’s major research interests include the Mould & Die CAD/CAE/CAM,modeling design and controlof deformation processes from micro to macro scale,tribology,simulation-based designand designoptimization.
His work has made some contributions to the understanding of scale effect in microforming and the effects of material microstructure and process parameters optimization on forming processes. This involves the study of the constitutive equation and the prediction of forming quality of formed micro-component as a function of process variables. His research has integrated experiment, analytical and numerical simulation methods to investigate fundamentals in material deformation and material formability at various scales, to advance the adaptive method and apparatus for microforming metal parts. Emphasis is placed on new miniaturized forming equipment, processes and tooling. Specific current research includes the development of laser micro-forming processes and of miniaturized micro/meso-scale tools and die/mould for the manufacture of components in the 10 – 1000 μm range.
His achivement have been recognized by honors and awards given by the government and peers in the field of mechanical engineering. His work has been funded both by government agencies and industries.
