Characteristics of Excimer Laser Ablation for Three Dimensional Machining of PMMA
In this research, machining characteristics of excimer laser ablation for three-dimensional machining of PMMA (Polymethyl methacrylate) is examined. In general, excimer laser ablation of polymeric material has features such as high precision and fine surface quality resulting from a less thermally-affected process, but in an earlier study, a thermal like effect on ablated surface was observed. Therefore, in this research the best machining condition of excimer laser ablation for PMMA by both numerical and experimental approaches was revealed.
