The development of new manufacturing processes and process enhancements at the micro/meso-scale has expanded considerably in recent years due to the demand for miniaturized products. With this increased demand comes a critical need for a fundamental understanding of the role these reduced length scales play in the various process mechanisms. Significant research has been recently performed on a wide range of micro/meso-scale manufacturing processes to understand the role of the tribological effect, size effect and other mechanisms on process performance. This paper reviews the research and state-of-the-art for micro/meso-scale mechanical cutting and related machine technologies, micro-EDM, laser micro-machining and laser shock peening, microforming, and micro-scale bio-manufacturing and polymer fabrication. These latter areas may be of particular interest as they have not received as much attention as the traditional process areas.
