1.
In the drilling process, the power spectrum of a drilling force is closely related to the drill wear.
在钻削过程中,钻削力功率谱与钻头磨损之间具有较强的相关性,被广泛用于钻头磨损监测,但是关于功率谱特征的提取和识别一直没有很好解决。
2.
In this paper,the cutting force signals in different drill wear conditions are decomposed and reconstructed using wavelet transform; and the changing characteristics of cutting force signals of time domains in different frequency bands are obtained.
