Numerical simulation of temperature at drilling micro-hole on moving CO 2 laser irradiated sticking plaster

Abstract

This paper applied numerical simulation of temperature by using finite element analysis software Ansys to study a model of drilling on sticking plaster. The continuous CO 2 laser doing uniform linear motion and doing uniform circular motion irradiated sticking plaster to vaporize. The sticking plaster material was chosen as the thermal conductivity, the heat capacity and the density. For temperatures above 450 °C, sticking plaster would be vaporized. Based on the mathematical model of heat transfer, the process of drilling sticking plaster by laser beams could be simulated by Ansys. The simulation results showed the distribution of the temperature at the surface of the sticking plaster with the time of vaporizing at CO 2 laser to do uniform linear motion and to do uniform circular motion. The temperature of sticking plaster CO 2 laser to do uniform linear motion was higher than CO 2 laser to do uniform circular motion in the same condition.
