本文提出了一种创新的系统，能够测量在磨削操作或修整过程中，砂轮和工件（或修整工具）之间的相互作用是否均匀。测量由基于声发射信号的信号处理系统执行。该系统处理高频AE信号的高速RMS水平。该软件绘制砂轮表面周围的RMS值，并显示3D图。该图用色标在线绘制了车轮和工件之间的交互水平。 从图表中提取的几个输出参数允许机器操作员或自动监控系统控制砂轮周围的磨损过程以进行校正。该系统主要应用于高速CBN磨削，其中砂轮周长的均匀使用是一个重要问题。

This paper presents an innovative system that is able to measure how uniform is the interaction between the grinding wheel and the workpiece (or dressing tool) during a grinding operation or dressing. The measurement is performed by a signal processing system based on acoustic emission signals. The system processes high speed RMS levels of high frequency AE signals. The software maps the RMS values around the grinding wheel surface and shows a 3D diagram. The diagram maps on-line with a color scale the interaction level between wheel and workpiece along the time. Several output parameters extracted from the diagram allow the machine operator or an automatic monitoring system to control the wear process around the grinding wheel for correction. The main system applications are in high speed CBN grinding where the uniform usage of the wheel perimeter is an important issue.
