硬质合金PA30高速深磨过程中声发射信号特征的变化研究
Characteristic changes of acoustic emission (AE) signal during high speed deep grinding of cemented carbide PA30
摘要
Abstract
In acoustic emission(AE) experiment on high speed deep grinding cemented carbide PA30, which is a hard difficult-to-machine material, the root-mean-square characteristic parameters of acoustic emission signal(AERMS) and grinding force increase as the workpiece speed and the depth of cut increase, while they decrease as the wheel speed increase.Therefore, the grinding force and the AERMS have the same change tendency.The spectrum energy of the acoustic emission signal when high speed deep grinding cemented carbide PA30 is focused on 100~600 kHz spectral ranges.The energy and frequency range of the AE signal spectrum are larger than that in low speed shallow grinding.关键词
