9424569 Busch-Vishniac This project will use a new six degree of freedom sensor based on lateral effect silicon photo sensitive diode (PSD) technology, to measure dimensions on manufactured mechanical components. For a high volume production environment, the innovation is in meeting the technical performance specifications. Resolutions on the order of 0.01-0.l micrometer over a linear range of +/- 30 mm and angular resolutions on the order of 0.01 arc-seconds over a rotation range of +/- 2 degrees are possible, and because these are primarily analog sensors, the goal is to make 1000 measurements a second so that it is feasible to use them for feedback process control in high volume production. This project will address three topics of importance in achieving these technical goals relevant to manufacturing: an error analysis of the integrated sensor system, implementation and robustness issues when installed in a manufacturing environment, and detection of dimensions, as well as position, of a fabricated part. To test the robustness issues, the investigators will work with a company to develop and install a prototype system in a pilot manufacturing environment. Successful completion of this project will provide a new resolution, high speed, non-contact sensor technology at modest cost. This enables closed loop control of dimensional or mechanical features in manufacturing and assembly systems that produce high volume and high quality products and components.

小行星9424569 该项目将使用一种基于横向效应硅光敏二极管（PSD）技术的新型六自由度传感器来测量制造的机械部件的尺寸。 对于大批量生产环境，创新在于满足技术性能规格。 在+/-30 mm的线性范围上的0.01- 0.1微米量级的分辨率和在+/-2度的旋转范围上的0.01弧秒量级的角分辨率是可能的，并且因为这些主要是模拟传感器，目标是每秒进行1000次测量，使得在大批量生产中将它们用于反馈过程控制是可行的。 该项目将解决三个主题的重要性，在实现这些技术目标相关的制造：集成传感器系统的误差分析，实施和鲁棒性问题时，安装在制造环境中，检测的尺寸，以及位置，制造的一部分。 为了测试鲁棒性问题，研究人员将与一家公司合作，在试点制造环境中开发和安装原型系统。 该项目的成功完成将以适中的成本提供一种新的分辨率，高速，非接触式传感器技术。 这使得能够在生产大批量和高质量产品和部件的制造和组装系统中对尺寸或机械特征进行闭环控制。
