摘　　要：激光打孔作为在金属上制备各种大小和形状的孔的有效方法,在现代制造业中得到了广泛使用。而准连续波激光相比于连续波激光具有更低的平均功率以及更高的峰值功率,打孔过程中的热效应小,更为适合精密加工;而与短脉冲激光或超短脉冲激光相比,准连续波激光拥有更快的加工速度。因此准连续波激光在激光打孔中具有重大的发展潜力。本文总结了准连续波激光打孔时的激光参数变化对打孔质量产生的影响,以及其他工艺与打孔质量的关系。Laser drilling is widely used in modern manufacturing as an effective method for preparing holes of various sizes and shapes in metal.Compared with the CW laser,the quasi-CW laser has lower average power and higher peak power,less thermal effect in the drilling process,which is more suitable for precision processing;and compared with the short pulse laser or ultrashort pulse laser,the quasi-CW laser laser has faster processing speed.Therefore,quasi-CW laser has great potential in laser drilling.This paper summarizes the effect of laser parameter variation on drilling quality during quasi-CW laser drilling,as well as the relationship between other processes and drilling quality.
