| 摘 要： | 本文通过对激光打孔的有关参数进行统计分析表明,焦距的调整距离、材料厚度及介质压力等参数对成孔形状有明显影响。如何综合考虑来选择这些参数,是激光打孔有待解决的问题。本文作者通过试验来说明对不同材料激光打孔时,其最佳焦距调整值与空气介质和氧气介质的压力大小及材料的厚度之间的关系。试验结果表明,在所有不同的介质压力下,最佳焦距调整值仅随材料厚度的增加而减少。

| Abstract: | By experiments, author explained the relationship among the optimal adjustment value of focal length, the medium pressure of air and oxygen and the thickness of work, when different material is hold. The results of experiments show that at ang medium pressure, the optimal adzustment value of focal length decreases only by the increasement of material thickness. |
