Research on Laser Micro Machining Polystyrene Material

Owing to drilling capacity can reach micron grade, laser punching technology has been widely used in high-tech field. In this article, ultraviolet laser has been adopted to punch on polystyrene material, the ablation principle and heat transfer between ultraviolet laser and material are analyzed. Through the finite element simulation, microporous temperature field distribution can be obtained. At last, by experiments that use single factor method to get laser parameters on the effect of surface morphology and microporous depth/diameter ratio, the optimal laser parameters that satisfy requirements which are less slag and tapered micropore can be acquired.
