| Abstract: | According to point of original sampling signal including multiplefrequency component in the noncontact measurement of roundness error,the filtering processing of the signals transformed by wavelet is proposed.A approach of using wavelet transform for original signal filtering is proposed.The basic principle and the step to carry out of fast wavelet transform are introduced.The evaluation rule for roundness error by means of least squares meancircle base on wavelet transform is discussed,and model of roundness error is processed.By taking advantage of the examination,the method and effect of deposing roundness error by wavelet transform are illustrated. |
