MRI: Acquisition of an Accordion Fringe Interferometer for Discrete Part Metrology

这笔赠款将用于购买手风琴条纹干涉仪(AFI)，用于离散零件制造中的几何公差验证。在这项研究中，AFI将被开发为传统计量工具的替代工具。将分析精度、量程和分辨率问题，以得出计量和公差验证的标准。这项研究的主要行动计划是通过仔细的研究分析，开发利用AFI进行飞机部件等中大型零件公差验证的知识库。特别感兴趣的是用于验证尺寸、形状、方向和位置的公差的方法和数学模型。然后，开发的数学模型将用于特征验证，并进一步扩展到基于零件的检查，以确保正确的“形式、匹配和功能”。将进行详细的实验分析，以验证其适用于各种不同的应用。评估计划将用于改善研究贡献、研究培训和传播。将规划和执行使用和维护时间表。这项研究有望带来更新的计量解决方案，并有望应对航空航天、汽车和生物医药行业面临的检查挑战。这项研究将导致更好的工艺和制造机器的设计。传统测量和逆向工程(RE)的替代方法的发展是可望的。这项研究将被适当地部署到教育中，并将导致尖端研究培训。这也将成为创建工业/大学实验室的基础，以更好地满足飞机支持行业的需求，从而为大学和俄克拉何马州在精密计量和RE方面创造一个利基市场。

This grant will fund the acquisition of an Accordion Fringe Interferometer (AFI) for geometric tolerance verification in discrete part manufacturing. AFI will be developed as an alternative to conventional metrology tools in this research. Issues of accuracy, range, and resolution will be analyzed to derive standards for metrology and tolerance verification. The primary action plan of this research is to develop the knowledge base for tolerance verification of medium to large sized parts such as aircraft components using an AFI, through careful research analysis. Of particular interest are methods and mathematical models for verification of tolerances of size, form, orientation and location. Then the mathematical models developed will be used for feature verification and further extended to part-based inspection to ensure proper 'form, fit and function'. Detailed experimental analysis will be conducted to verify suitability to a varied set of applications. Evaluation plans will be used to improve the research contributions, research training, and dissemination. Utilization and maintenance schedules will be planned and executed.This research is expected to lead to newer metrology solutions and holds significant promise to inspection challenges faced by aerospace, automotive, and biomedical industry. This research will lead to a better design of processes and manufacturing machines. The development of alternate methods for traditional measurement and Reverse Engineering (RE) is expected. The research will be suitably deployed into education and will result in cutting-edge research training. This will also serve as a building block for creating an Industry/University laboratory to better meet the demands of aircraft-support industry, thereby creating a niche for the university and the State of Oklahoma in precision metrology and RE.
