This grant provides support for the acquisition of a LDI CMM laser scanning probe kit, a cluster of six HP high-end dual-processor workstations and a 40'' glasses-free 3D monitor (SynthaGram 404) for multidisciplinary manufacturing-related research at the University of Michigan - Dearborn (UM-D). The requested instruments will form a fundamental infrastructure of a new virtual engineering laboratory, and will support ongoing research activities in virtual engineering, including accurate measurement or acquisition of manufactured parts, surface quality inspection and reengineering of broken parts, simulation of fracture and damage, analysis of manufacturing processes, intelligent engineering diagnosis and vision-based inspection or recognition. The main objective of these studies is to develop innovative algorithms for meeting the manufacturing society's growing demands for high accuracy and automation by making effective use of the extremely powerful sensor, computers and visualization device to be acquired. The outcome of the ongoing research activities will lead to: 1) a potential breakthrough in replacing touch probes with laser sensors mounted to coordinate measurement machines (CMMs); 2) a virtual surface quality evaluation system for sheet metal forming; 3) a refurbishing and reengineering system for broken parts; 4) an intelligent vision-based system for inspection and recognition; and 5) fuzzy learning for engineering diagnosis. The ongoing research will also contribute to the modeling of fatigue life of solder alloys and the understanding of deformation behavior from localized necking to fracture in metal forming by means of the requested computers and visualization device. The requested instruments will substantially strengthen the research infrastructure at UM-D, a non-Ph.D. granting institute, and will also significantly improve the education quality at UM-D through student design projects and research training. The community outreaching will inspire high-school students' interest in science and engineering, and broaden the participation of underrepresented black minority and female students in Dearborn and Detroit communities.

这笔拨款为密歇根大学迪尔伯恩分校（UM-D）的多学科制造相关研究提供了LDI CMM激光扫描探头套件、六个惠普高端双处理器工作站集群和一个40英寸裸眼3D监视器（SynthaGram 404）的支持。所要求的仪器将构成一个新的虚拟工程实验室的基础设施，并将支持正在进行的虚拟工程研究活动，包括精确测量或获取制造零件，表面质量检查和损坏零件的再工程，断裂和损伤的模拟，制造过程的分析，智能工程诊断和基于视觉的检查或识别。这些研究的主要目的是通过有效利用极其强大的传感器、计算机和可视化设备，开发创新的算法，以满足制造社会对高精度和自动化日益增长的需求。正在进行的研究活动的结果将导致：1)在用安装在坐标测量机（cmm）上的激光传感器取代触摸探针方面取得潜在突破；2)钣金成形虚拟表面质量评价系统；3)对损坏部件的翻新和再造系统；4)基于智能视觉的检测识别系统；5)模糊学习用于工程诊断。该研究还将通过计算机和可视化设备对焊接合金的疲劳寿命进行建模，并对金属成形过程中从局部颈缩到断裂的变形行为进行理解。所要求的仪器将大大加强UM-D的研究基础设施，非博士。，并将通过学生设计项目和研究培训，显著提高澳大的教育质量。社区外展活动将激发高中生对科学和工程的兴趣，并扩大迪尔伯恩和底特律社区中代表性不足的黑人少数族裔和女学生的参与。
