Abstract
A dual laser beams method was proposed to reduce the thermal stresses when machining glass with CO2-laser. A numerical method based on Ansys software was used to simulate temperature and thermal stresses in glass. Thermal stresses in glass with and without CO2-laser preheating have been studied. The results showed that machining glass with dual laser beams could reduce thermal stresses.
