A thermal model of a single pulse laser drilling process by using finite element method is presented. Some parameters such as conduction, convection, thermal properties of material with temperature and gauss distribution of heat flux has been considered in the laser drilling process. The simulation result shows the trend of dynamic temperature distribution of heat-affected zone, and by using the element birth and technique, the geometry size of the hole could be predicted in the simulation. Through the comparison between the simulation results and the actual experiment process results, the validity of the simulation model has been verified. |
