It is very considerable to predict the processing parameters from the numerical simulation of laser micro-polishing on the metallic surface. In this paper, we have in detail investigated the numerical simulation method of the polishing process during laser micro-polishing of the metallic surface with UV nanosecond pulse laser. We have also numerically simulated and analyzed the laser micro-polishing processing on three different metals (stainless steel 316L, pure nickel, and pure titanium) to predict the processing parameters, such as the behavior of the surface material melting front and the range of suitable energy density for the micro polishing. In addition, the laser micro-polishing experiments on those metallic surfaces were conducted using UV nanosecond pulse laser, to prove experimentally the results of numerical simulation. From the comparison between the numerical simulation and experimental results, the minimum melting energy density for a single laser pulse 40 ns in duration, for stainless steel 316L, Ti and Ni, are 0.45 J/cm², 0.37 J/cm²_, and 0.84 J/cm², respectively.
