CAREER: Abrasive Flow Machining

这项研究的目的是制定与磨料流加工(AFM)发展相关的平衡和综合的研究和教育目标。研究内容包括：(1)利用粘弹性载体的磨损机理和特性建立原子力显微镜的过程模型；(2)将声发射监测扩展到多通道和新材料；(3)探索原子力显微镜在光固化原型后处理加工中的潜在应用。在教育方面，将把合作学习方法纳入选定的制造课程的课程中，并将开发两个新课程，即高级计算机辅助工艺设计和环境意识制造。研究和教育计划的结果将被制定成基于互联网的软件试验床和入门读物，供教职员工、学生和行业工程师使用。迫切需要灵活的精加工工艺，能够在各种材料和各种加工条件下处理复杂、精确的几何形状。AFM已被证明在有限的应用范围内有效地满足了这一需求。全面的研究和教育努力是发展原子力显微镜必要的科学知识和技术基础以充分发挥其应用潜力所必需的。

The objective of this research is to develop balanced and integrated research and education goals related to the development of Abrasive Flow Machining (AFM). The research studies are to: (1) develop a process model for AFM utilizing wear mechanisms and characteristics about the viscoelastic carrier, (2) expand the acoustic emission monitoring to multiple passages and new materials, and (3) investigate the potential application of AFM for post-process finishing of stereolithography prototypes. On the education side, cooperative learning methodologies will be integrated into the curriculum for select manufacturing courses, and two new courses, Advanced Computer-Aided Process Planning and Environmentally Conscious Manufacturing, will be developed. Research and education program results will be formulated into Internet-based software testbeds and primers accessible to faculty, students and industry engineers. There exists a vital need for flexible finishing processes that are capable of handling intricate, precise geometries with a wide range of materials and in a variety of machining conditions. AFM has proven effective in fulfilling this need in a limited range of applications. A comprehensive research and education effort is essential to develop the necessary scientific knowledge and technology base of AFM to realize its full application potential.
