Abstract
Polymer materials are applied in broad field due to the high functionality, however easily affected by heat or forces in processing. On the other hand, laser processing is used in many fields. Laser ablation is focused in this study, because it prevents to get form damage by the heat and PMMA(Polymethylmethacrylate) was used as work piece. Machining characteristics of PMMA are experimentally investigated, while ablation process is analyzed considering photochemical effects. The optimal process conditions for PMMA are investigated by comparing calculated results with experimental ones. Finally the possibility of 3–dimensional form generation of laser ablation for polymer was discussed.
