The Choice of Wavelet Bases for Singular Signal Detection

Singular signal always brings some important information in the diagnosis field and wavelet is an useful tool to detect singularity. Several wavelets' effect on singularity detection is analyzed and compared with each other in this paper. Based on these results, the best wavelet base is recommended according to the characteristic of different singular signal. And the cutting force signal, which is the singular signal when the tool is worn, is used to test the performance of these wavelet bases.
