| Abstract: | The paper introduces the features of the wavelet transform in contrast to the FT.Combining with tool breakage signal, the fast wavelet transform-Mallat algorithm is analyzed. Wavelet transform is used to analyze the signal of tool breakage in numerical control machine tool. Experimental results show that the method of MRA can not only locate the position on time-frequency domain,but also easily monitor the manufacturing system. The method can be applied effectively to signal processing of monitoring tool breakage. |
