Abstract

The micro-convexity isotropy of surface topography influences the function performance of the engineering surface greatly. In this paper a evaluation method is proposed which is based on the application of fractal geometry thorey. Through the Fourier transform of the discreate data of the profile measured by the stylus instrument we obtained the po''''er spectrum and the fractal dimension of the profile. And then the spectral moments of the profile and the surface are found. By these patameters the evaluation method is proposed. This study shows that the micro-convexity of the surface topography processed by precision rolling is anisotropic Key Words Isotropy Evaluation Precision Rolling Process Fractal Dimension Power Spectrum Moment
