U.S.-Singapore Cooperative Research on Automatic Fixturing

小行星9215993 该奖项提供资金，以允许露西萧碧金博士，工业和制造系统工程系，GMI工程和管理学院，和博士金曼E。2009年10月，劳伦斯理工大学机械工程系Yee博士与新加坡南洋理工学院GINTIC计算机集成制造研究所的Beng Siong Lim博士合作，进行为期24个月的自动夹具研究项目。 他们的研究将针对两个主要目标，即（1）理论制定的优化模型，以找到一个给定的工件几何形状的夹具元件的位置和（2）比较夹具元件与夹具组件使用MOFDEX专家支持系统，块夹具系统，和模块化夹具系统。 在PI以前的研究中，已经开发了一个优化模型来生成棱柱形物体的夹具配置设计。 本研究将延伸至非棱柱形工件，如球体、圆柱体、四面体及平行六面体，并考虑装配操作及装夹元件类型。 Lim博士为第二个目标的实践部分开发了专家系统。 在制造环境中仍然流行的手动固定方法可能会导致汽车工厂三到六周的延迟。 并行工程和柔性制造要求更快的周转时间夹具设计。 自动夹具配置提供了这样的需求的部分解决方案。 从这种合作产生的专家支持系统将是特别有用的计算机辅助夹具在使用CAD（计算机辅助设计）系统的行业。 合作者有互补的专业知识，这将是互惠互利的研究。 该项目与国际方案司的目标有关，该司力求通过科学信息、思想、技能和技术的交流以及通过在互利问题上的合作，提高美国科学家和工程师与发展中国家同行之间的合作水平。 该项目为金博士在NSF赠款号DDM-9196231和DDM-9215362下的研究增加了国际合作的层面。 ***

9215993 King This award provides funds to permit Dr. Lucy Siu-Bik King, Department of Industrial and Manufacturing Systems Engineering, GMI Engineering and Management Institute, and Dr. Kingman E. Yee, Department of Mechanical Engineering, Lawrence Technological University, to pursue with Dr. Beng Siong Lim, GINTIC Institute of Computer Integrated Manufacturing, Nanyang Technological Institute, Singapore, for a period of 24 months, a program of research on automatic fixturing. Their research will be directed toward two major goals, namely, (1) the theoretical formulation of an optimization model for finding the positions of fixturing elements for a given workpart geometry and (2) comparing the fixturing element with fixture components using the MOFDEX expert support system, the Block Jig System, and Modular Fixturing System. In the PI's previous research, an optimization model has been developed to generate a fixturing configuration design for prismatic objects. This research will be extended to non- prismatic workparts such as the sphere, cylinder, tetrahedron and parallelpiped taking into account assembly operations and fixturing element types. Dr. Lim has developed expert systems for the practical portion of the second goal. Manual methods of fixturing, still prevalent in the manufacturing environment, may result in delays of three to six weeks in an automotive plant. Concurrent engineering and flexible manufacturing requires faster turn around time for fixturing design. Automatic fixturing configuration offers a partial solution to such a demand. The expert support system generated from this collaboration will be especially useful for computer- aided fixturing in industries that use CAD (Computer Assisted Design) systems. The collaborators have complementary expertise which will be mutually beneficial in this research. This project is relevant to the objectives of the Division of International Programs which seeks to increase the level of coopera tion between U.S. scientists and engineers and their counterparts in developing countries through the exchange of scientific information, ideas, skills, and techniques and through collaboration on problems of mutual benefit. This project adds an international cooperative dimension to the Dr. King's research under NSF Grants No. DDM-9196231 and DDM-9215362. ***
