中文摘要：

在高精密平面磨床上,使用金刚石砂轮磨削SiCp/Al复合材料,通过PCI-1712高速数据采集卡采集实验数据.在Matlab软件里,通过对不同磨削参数下的信号进行时域和小波分析,得出在砂轮速度一定时,进给速度对磨削力和磨削力比的影响最大,磨削深度次之,实验结果表明：随着进给速度和磨削深度的增大、磨削力增大,磨削力比减小。

英文摘要：

SiCp/Al composite material was grinded with diamond wheel on high-precision machine. Acquiring grinding force signals of the experiment with high speed advantech PCI-1712 board. Acquired grinding force signals are analyzed in MATLAB which has mighty function disposing signals. Through analyzing the grinding force in time field and the signals wavelet analysis for different grinding parameters, found that the feed velocity has much more influence on the grinding force, the grinding force ratio and the standard deviation of the grinding force than the depth of grinding when the velocity of the diamond wheel is fixed. The result of the experiment indicates that the grinding force increases and the grinding force ratio decreases with the increasing of feed velocity and grinding depth.
