The micro-crack on surface of coniferous wood direct influence its surface integrity, that results in destruction of appearance or component failure during usage could have impact on service life and safety. It’s found one of main cause of such micro-crack is result from thermal stress. This paper demonstrate laser ablation effect on the microcosmic surface by numerical simulation which set up model of coniferous wood’s surface by applying ABAQUS, to analyze the heat flux temperature field distribution of surface which was ablated by laser, acquire the ablation state of wood surface by means of the unique model, which define attribution, create analysis step, define interaction and load. Furthermore study on ablation effect in microcosmic surface by adjusting laser power and size of beam. Finally, verify the simulation results by means of existing lab working equipment.
