The objective of this collaborative research is to enhance the scientific knowledge of material properties, modeling, and manufacturing at the scale of a few millimeters to several microns in size. The results of this project will be a viable micro-forming process. The approach will combined fundamental and applied research with respect to physical interactions between workpiece and tool, processing parameters, and scaling effects of material properties, which prevent optimized macro-forming processes to be simply miniaturized to components on the micro/meso-scale. This knowledge will then be applied to devise a micro-forming process that will produce more accurate parts faster, for less cost, and with higher aspect ratios. The research results will be validated through extensive material testing, micro-forming system testing, and comparisons between the numerical simulation and experimental results. The knowledge gained through this research at the micro/meso-scale will lead to an effective and efficient micro-forming process. The implementation of such a micro-manufacturing process will lead to further micro-components and systems for biomedical, telecommunication, and environmental monitoring applications, which will benefit society as a whole. Also, the findings will be incorporated into university courses and disseminated through seminars, short courses, journal articles and the internet, which will contribute to the micro/meso-scale knowledge base. Finally, the undergraduate and graduate students involved with the research will benefit from the interactions amongst the academic (U New Hampshire, Northwestern U) and industry (Alcoa, GOALI partner) collaborators on this interdisciplinary project.

这项合作研究的目的是提高材料特性、建模和制造的科学知识，尺寸从几毫米到几微米。该项目的结果将是一个可行的微成形过程。该方法将基础研究和应用研究相结合，涉及到工件与刀具之间的物理相互作用、工艺参数和材料性能的比例效应，从而避免了将优化的宏观成形过程简单地微型化到微观/细观尺度上的组件。然后，这些知识将被应用于设计一种微成形工艺，该工艺将以更快的速度、更低的成本和更高的高宽比生产更精确的零件。研究结果将通过广泛的材料试验、微成形系统试验以及数值模拟和实验结果的比较来验证。通过这项研究在微观/细观尺度上获得的知识将导致有效和高效的微成形过程。这种微制造工艺的实施将带来更多用于生物医学、电信和环境监测应用的微元件和系统，这将造福整个社会。此外，研究结果将纳入大学课程，并通过研讨会、短期课程、期刊文章和互联网传播，这将有助于建立微观/中观知识库。最后，参与研究的本科生和研究生将受益于学术(U New Hampshire，西北U)和行业(Alcoa，Goali合作伙伴)在这一跨学科项目上的合作。
