摘要
利用SWAES声发射检测仪提取数控加工过程中金属切削声发射信号,对信号进行频谱分析,找出主要频段,并利用金属切削过程中的声发射模型及试验数据,对影响声发射信号的因素进行分析,指出进给速度和主轴转速对声发射信号影响较大。
Acoustic emission （AE） signals of cutting tools in numerical control （NC） machining process is extracted with SWAES, and the main frequency band of AE signals of cutting tools is gained after analyzing the spectrum of AE signals. Then, influencing factors to AE signals are analyzed with AE model and testing data, the results show that feed speed and spindle speed have a strong effect to AE signals of cutting tools.
