The paper introduces the features of the wavelet transform in contrast to the FT and FFT. Combining with tool breakage signal
the fast wavelet transform-Mallat algorithm is analyzed. It analyzes the technique of extracting the spindle motor current of the Machining Center
correspondingly
points out that Hall current sensor is a very efficient way. As the signal of tool breakage is transient
wavelet transform is used to analyze the signal of tool breakage in CNC milling and a successful example of the method is adduced to get the characteristics of the signal of tool breakage. Experimental results show that the method of MRA can not only locate the position in time-frequency domain
but also easily monitor the manufacturing system. The method can be applied effectively to signal processing of monitoring tool breakage.
