摘要
为了消除切削力信号中的随机噪声干扰,本文提出了一种基于卷积型小波包变换的消噪算法,给出了算法的详细步骤。对两个切削力信号的消噪实例结果表明:随机噪声已完全被去除,获得了准确的力信号。
In order to erase the disturbance of random noise in cutting force signal, a denoising algorithm based on the convolution wavelet packet transformation is put forward and the detail step of algorithm is given. The processing results of two cutting force signals show that the random noise is completely erased and the accurate force signals are obtained.
