A novel approach Laser Ablation Combined with Chemical Flow Etching is proposed. How laser pluses energy density, repetition rate, pulse width, scan velocity and other parameters cause the eclipsed quantity and the surface quality by combining etching method on metal materials is studied by using experiments. Moreover the effects of corrosive style, its concentration and rushing velocity and other flow parameters are also analyzed in combining process. Experimental results show that the new approach is inspiring in enhancing surface quality and machining velocity. It is obvious that the liquid is the important factor of reducing lags and roughness, also of increasing eclipsing quantity.
