This grant is to purchase a physical acoustic high-frequency data acquisition and signal process system for the investigation of in-process abrasive damage assessment techniques using acoustic emission. The equipment will enable the research conducted by the Abrasive Micro-Machining Center at Kansas State University to obtain acoustic emission data well beyond the audible range, thereby facilitating efforts to analyze the full range of data generated by the acoustic emission signals. The system will be used to investigate innovative methodologies for identifying the acoustic emission signatures associated with workpiece subsurface damage in conventional and non-conventional abrasive process of ceramics and steels and to develop acoustic emission methods for in-process damage assessment and control. The acoustic emission data acquisition and signal process system substantially enhances the research capability of the Abrasive Micro-Machining Center at Kansas State University for understanding subsurface damage in conventional and non-conventional abrasive process of ceramics and steels. It is also valuable to the development of acoustic emission methods for in-process damage assessment and control.

这笔拨款是为了购买一个物理声学高频数据采集和信号处理系统，用于研究使用声发射的过程中磨料损伤评估技术。该设备将使堪萨斯州立大学磨料微加工中心进行的研究能够获得远远超出可听范围的声发射数据，从而有助于分析声发射信号产生的全范围数据。该系统将用于研究在陶瓷和钢的常规和非常规磨料过程中识别与工件亚表面损伤相关的声发射特征的创新方法，并开发用于过程中损伤评估和控制的声发射方法。声发射数据采集和信号处理系统大大提高了堪萨斯州立大学磨料微加工中心对陶瓷和钢的常规和非常规磨料加工过程中亚表面损伤的研究能力。这对发展声发射方法进行过程损伤评估和控制也有价值。
