A new approach based on the combination of wavelet and fractal theories is proposed. The purpose is to provide a mechanism to evaluate the characteristics of engineering surfaces more accurately and comprehensively. The wavelet transformation models and the fractal representation of engineering surfaces are presented and the combination of the wavelet models and the fractal representation is investigated. Using the proposed approach, the experimental samples of the workpiece surface obtained through grinding are examined. The results demonstrate that the proposed approach is accurate and comprehensive.
