摘　　要：基于零件中小孔磨削加工的特点,探讨应用AE声发射传感器作为信号采集手段构建中小孔磨削监控系统的方法。结合其在Z2-015数控精密内圆磨床的应用分析,阐述了AE传感器的选型方法及选型关键参数。采用实验的方法,在机床三种不同的安装位置上,分别测量了工件磨削加工过程中AE信号的电压值、频宽及截止频率大小,进而确定了AE传感器的适宜安装位置及方法。Based on the characteristies of the grinding parts with middle-small holes, the AE sensor for grinding monitoring system is applied in signal acquisition. Combined the analysis of AE sensor installed in the precision NC internal grinder of Z2-015, the selection methods and key parameters of AE sensor are proposed. Experimental method is used to measure the voltage, frequency width and highest frequency of AE signals which installed in three different positions are measured during the process of internal grinding, and then the appropriate installation positions and methods of AE sensors are got.
