| 摘 要： | 为了探究Al_2O_3陶瓷的激光切割工艺特性,采用Nd:YAG激光器对Al_2O_3陶瓷进行加工试验。先通过打孔试验计算获得Al_2O_3陶瓷的激光烧蚀阈值,再通过切割试验分析激光功率、切割速度、脉冲频率、离焦量等工艺参数对切割质量的影响规律。结果表明:通过优化激光切割工艺参数,可在保证切割效率的同时,提高Al_2O_3陶瓷的切割质量。

| Abstract: | In order to explore the Al2O3 ceramic laser cutting technology characteristics ,processing experiments of cutting Al2O3 ceramic with Nd: YAG laser were carried out. Firstly ,the laser ablation threshold of Al2O3 ceramics was obtained by drilling experiment. After that,the effects of laser power, cutting speed,pulse repetition rate and defocusing amount on cutting quality were analyzed though the cutting experiment. The results show that the laser cutting quality of Al2O3 ceramic can be improved by optimizing the process parameters ,while the efficiency was guaranteed. |
