Simulation of Drilling Micro-Hole by a Dual CO₂ Laser Beam Irradiated Sticking Plaster

Abstract:

We explore a simulation model of drilling micro-hole in sticking plaster heated with a dual CO2 laser beam. This paper applied numerical simulation of temperature by using finite element analysis software Ansys to study a model of drilling on sticking plaster. A dual CO2 laser spot sizes ranged from 0.15 to 0.2mm radius with axial irradiance power levels of 50-100w. For temperatures above 450°C, sticking plaster would be vaporized. The size of ventilation holes changed with beam power and laser spot diameter. The width of the hole is increases with the increasing laser diameter and with the increasing laser power. These results can guide to laser drilling experiments.
