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.

这项合作研究的目标是在几毫米到几微米的尺度上提高材料特性、建模和制造的科学知识。该项目的结果将是一个可行的微成形工艺。该方法将结合工件和工具之间的物理相互作用，加工参数和材料性能的缩放效应方面的基础和应用研究，防止优化的宏观成形过程简单地小型化到微/中观尺度上的部件。这些知识将应用于设计一种微成形工艺，以更快的速度生产更精确的零件，成本更低，纵横比更高。研究结果将通过广泛的材料测试、微成形系统测试以及数值模拟和实验结果的比较来验证。通过在微/中观尺度上的研究获得的知识将导致一个有效和高效的微成形过程。这种微制造工艺的实施将导致进一步的微部件和系统用于生物医学、电信和环境监测应用，这将使整个社会受益。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/中尺度知识库。最后，参与研究的本科生和研究生将从这个跨学科项目的学术（新罕布什尔大学、西北大学）和行业（美国铝业公司、GOALI合作伙伴）合作者之间的互动中受益。
