GOALI/Collaborative Research: Microforming Processes - Fundamental Studies and Developments

这项合作研究的目的是提高材料性能，建模和制造的科学知识在几毫米到几微米的尺寸。 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，这将防止优化的宏观成形工艺被简单地小型化为微/中尺度上的组件。然后，这些知识将被应用于设计一种微成形工艺，该工艺将以更低的成本更快地生产出更精确的零件，并具有更高的纵横比。 研究结果将通过大量的材料试验、微成形系统试验以及数值模拟与试验结果的对比得到验证。通过这项研究在微观/介观尺度上获得的知识将导致有效和高效的微成形过程。 这种微型制造工艺的实施将导致用于生物医学，电信和环境监测应用的进一步微型部件和系统，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，这将有助于建立微观/中型知识库。 最后，参与研究的本科生和研究生将受益于学术（U新罕布什尔州，西北大学）和工业（美铝，GOALI合作伙伴）合作者之间的互动。

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.
