Functional Characterization of Surface Roughness Generated by Plateau Honing Process Using Wavelet Analysis

Plateau honing is being widely used in the production of cylinder bores to produce a surface to achieve the required functional performance. Characterizing plateau-honed surface irregularity into functional components is helpful for process control and functional analysis. The application of wavelet transform to characterize plateau-honed surface is presented. Difficulty exists in quantitatively determining the zooming level for functional characterizing the multi-process produced surfaces. In this paper, we utilize probability plot of bearing ratio curve, to quantify the zooming level of wavelet transform to obtain the functional components which related to different functional aspects from plateau honed surfaces. The effectiveness of this method is demonstrated.
