Based on the principles of co2 laser machining polymer , heat conduction theory and energy conservation principal at the ablation front , a three dimensional transient ablation model of laser machining was built 在co2激光加工聚合物原理基礎上,根據傳熱學原理和燒蝕面能量守恒原理,建立了激光加工三維暫態燒蝕模型。
Groove shape function of laser power , scanning velocity and materials ' thermo physical coefficients was solved due to temperature at ablation front keeping decomposed temperature , and the proposed model was tested in polymethylmethacrylate experiment 基于燒蝕面上的溫度始終保持為降解溫度,求出關于激光功率、掃描速度和材料熱物理系數的微流道外形函數解,并用聚甲基丙烯酸甲酯進行了實驗驗證。
