摘要:
采用不同锯切参数对G603,G657,G654三种花岗石进行锯切实验,监测锯切过程工件上声发射信号和锯机主轴功率消耗,并以声发射均方值(AERMS)为特征值对实验结果进行分析.结果表明:锯切过程中,AERMS随着锯切深度和进给速度的增大而增大,随着锯片线速度的增大而减小;与锯切功率具有良好的线性正相关对应关系;不同花岗石锯切时,AERMS随锯切参数的变化趋势一致,但幅值存在明显差异,花岗石的抗压强度越高,AERMS值越大.
Abstract:
Using different parameters, sawing experiments were carried out on three kinds of granites(G603, G654, G657), and acoustic emission(AE)and spindle power consumption were monitored during sawing processes. The experimental results were analyzed with the mean square value of AE(AERMS). The results show that AERMS increases with the increase of sawing depth and feeding speed, but decreases with the sawing speed, and has a good linear positive correlation relationship with sawing power. In sawing of different granites, AERMS tendencies with different sawing parameters are the same but thers is obvious difference in amplitude. And the higher the compressive strength of granite is, the larger the value of AMRMS becomes.
