| Abstract: | The basic theory of wavelet analysis and wavelet reduce to noise are expounded. The cutting force singal analysis method is put forward based on wavelet transformed aiming at the flaw of fourier transformed and instant fourier transformed. Wavelet muliti-differentiate analysis can perform time and frenquency fields decomposed of random precision and scale of PCBN tools cutting force singal, judge the cutting state of PCBN tools, adjust cutting parameter and decrease tools wear and tear according to the different feature of cutting force singal and exposes distributing feature of typical cutting force singal. |
