摘要
利用ＣＯ２激光连续脉冲频率的快慢，平均功率的大小，加上辅助空气吹气压力的变化及其之间的交互作用。
CO 2 laser is a desirable tool to drill ceramics such as Al 2O 3. Drilling of Al 2O 3 ceramics has several problems to be solved: such as high melting point, high hardness degree and crack coming from thermal shock. This study investigates the influence of factors such as frequency of pulses, laser average power and the pressure of assistant air on the quality of drilling. Their mutual influence on the hole size is discussed.
