Abstract

Temperature field analysis of laser micro-drilling is a nonlinear transient thermal conduction problem with phase changing. In this paper, first the temperature field is simulated with ANSYS finite element analysis software, thus obtaining a three-dimensional temperature field distribution. By analyzing the temperature values of the laser irradiated surfaces, with holes having different diameters, depths and directions, we obtained the law that the temperature varying with time. Finally the temperature variation rate is calculated with the above information. To verify the above simulation and analysis result, laser micro-drilling experiments are conducted. In the tests, the holes’ diameter and depth are measured, and their relationship with the measurement laser pulse number is analyzed. Test result shows that the simulation result is correct, thus providing a theoretical evidence for enhancing the dimensional accuracy and surface quality of laser micro-drilling.
