This AIR project will bring to commercial prototype stage a new machining-based process, Modulation-Assisted Machining (MAM), for large-volume production of metal fibers. By super imposing low-frequency modulation onto a sharp tool, individual fibers having highly uniform size and shape are created by cutting in a single-stage deformation process. The key research objectives that will be addressed in the proposed work are: 1) scalability of the production rate for creating fibers, 2) repeatability of fiber size and shape under commercial production rates; and 3) and life-cycle analysis related to the modulation device at rates typical of production. The MAM platform offers a unique ability to produce metal fibers with controlled size at high production rates compared to traditional multi-step drawing processes. A prototype method for large-scale production of fiber materials will be demonstrated, while transforming machining technology across business sectors and opening a new applications domain for machining production of advanced materials. MAM offers a low cost production route and a process breakthrough for producing fibers that are difficult to create using current technology. The unique particle geometries and structure created by MAM will enable new commercial opportunities for production of fiber-based products, and composite material systems. Complementing the research is an education and training program involving company internships for graduate and undergraduate students. The collaborative research will expose the students to advanced materials processing and related commercialization, and the dynamic environment of a recent manufacturing start-up company

这个AIR项目将把一种新的基于加工的工艺——调制辅助加工（MAM）——带入商业原型阶段，用于大规模生产金属纤维。通过在锋利的刀具上施加低频调制，在单阶段变形过程中切割出具有高度均匀尺寸和形状的单个纤维。提出的工作将解决的关键研究目标是：1)纤维生产速率的可扩展性，2)在商业生产速率下纤维尺寸和形状的可重复性；3)与典型生产速率调制装置相关的生命周期分析。与传统的多步拉伸工艺相比，MAM平台提供了一种独特的能力，可以以高生产率生产尺寸可控的金属纤维。将展示一种大规模生产纤维材料的原型方法，同时改变跨业务部门的加工技术，并为先进材料的加工生产开辟新的应用领域。MAM提供了一种低成本的生产路线，并为生产使用当前技术难以制造的纤维提供了工艺突破。MAM创造的独特颗粒几何形状和结构将为纤维基产品和复合材料系统的生产带来新的商业机会。与研究相辅相成的是一项教育和培训计划，包括研究生和本科生在公司实习。合作研究将使学生接触到先进的材料加工和相关的商业化，以及最近制造初创公司的动态环境
