In order to predict the topography of the pulsed laser surface micro-texturing in carbon tool steel, the energy-balance equation, heat source mode, boundary conditions equation were established. Based on above mathematical model, temperature field and crater was simulated by the finite element analyzing software-ANSYS. The simulation results indicate that: As the laser intensity increases, the crater depth produced by single pulse increases. But there is an utmost depth of crater as the laser intensity increases; The crater depth almost linearly increases as the pulse count is under 10. But the depth growth rate becomes slower as it is above 10. The experiments were done in the same parameters with Nd: YAG laser. And the 3-D topography was measured with the Wyko System. The experiment results are consistent with the simulation results. This research lays a foundation for laser machining micro-texturing in a rapid and effective way.
