With continuous advances in engineering materials and the growing demand for miniaturization and economically viable products, research in manufacturing has several challenges to address. An important challenge in current manufacturing research is the development of new processes and related science for producing micro-scale parts and features in conventional and advanced engineering materials for various applications in medical devices, consumer electronics, and optics. Manufacturing process science, as applied to machining of three-dimensional micro-scale features and parts using conventional and advanced engineering materials, is however still in its early stages. In this talk, I will present our ongoing research on mechanical micromachining and laser-based hybrid methods. Specifically, I will discuss our work on understanding the origins of size effects in micro-scale material removal and present an innovative laser-assisted mechanical micromachining process for creating free-form features in very hard materials. In addition to micromachining, I will also discuss our work on breakage-free handling of silicon substrates of micron-level thickness for photovoltaic applications. I will conclude my presentation with brief highlights of other research in emerging areas of manufacturing.
