9411732 Webster The award is for the purchase of a high frequency data acquisition system to investigate in-process grinding damage assessment techniques using acoustic emission. Preliminary results have indicated that use of filtered signals is not adequate and that the full range of data generated by the acoustic emission signal must be used for effective assessment. The research enabled by the acquisition of the equipment requested will investigate innovative methodologies to identify signatures associated with workpiece burn and subsurface damage in conventional and creep-feed grinding of ceramics and steels. Detection of damage due to grinding is important since it is usually the final process to be carried out on a precision component. Greater control of grinding damage, by improved diagnostic procedures such as those sought here, is therefore of direct interest to all grinding-dependent industries as it would lead to lower scrap rates and cost savings.

小行星9411732韦伯斯特 该合同用于购买一套高频数据采集系统，以研究使用声发射的过程中磨削损伤评估技术。 初步结果表明，使用滤波信号是不够的，必须使用由声发射信号产生的全范围数据进行有效评估。 通过购买所需设备进行的研究将调查创新方法，以确定与陶瓷和钢的常规和缓进给磨削中工件烧伤和表面下损伤相关的特征。 由于磨削通常是对精密部件进行的最后加工，因此检测磨削造成的损坏非常重要。 因此，通过改进诊断程序（如本文所寻求的诊断程序）来更好地控制磨削损伤，对所有依赖磨削的行业都有直接意义，因为这将导致更低的废品率和成本节约。
