The processing parameters of laser texturing are linked with the wear property of rollersurface based on the relationship between the fractal parameters and surface roughness. Theinfluence of laser power density, scanning speed and pulse width on the roughness is analyzedthough experiments. The effect of fractal parameters on the wear rate of the roller is analyzed withfractal geometry model for wear prediction. Condition of achieving engineering surface withoptimal fractal dimension is presented and the expression of the optimal fractal dimension isderived. It shows that the roughness of laser textured surface and normalized wear rate are mainlydetermined by laser power density and fractal dimension, respectively. Moreover, to get the texturedsurface with smallest nominal wear rate, processing parameters of laser texturing, especially thelaser power density, should be controlled properly besides the material properties of the roller. Theresult will provide guidance for the processing
