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.

这笔拨款将资助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将作为传统计量工具的替代方案而发展。准确度、量程和分辨率问题将进行分析，以得出计量和公差验证的标准。本研究的主要行动计划是通过仔细的研究分析，开发使用AFI进行大中型零件（如飞机部件）公差验证的知识库。特别感兴趣的是验证尺寸、形状、方向和位置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，以确保适当的“形式，配合和功能”。将进行详细的实验分析，以验证对各种应用的适用性。评价计划将用于改进研究贡献、研究培训和传播。计划并执行使用和维护计划。这项研究有望带来更新的计量解决方案，并为航空航天、汽车和生物医学行业面临的检测挑战带来重大希望。这项研究将有助于更好地设计工艺和制造机器。传统测量和逆向工程（RE）的替代方法的发展是值得期待的。这项研究将适当地部署到教育中，并将导致尖端的研究培训。这也将作为创建工业/大学实验室的基石，以更好地满足飞机支持行业的需求，从而为大学和俄克拉荷马州在精密计量和可再生能源领域创造一个利基市场。
