合肥钣金切割加工小孔(直径小与板厚)变形情况的分析
 

这是因为机床(只针对大功率激光切割机)在加工小孔时不是采取爆破穿孔的方式,而是用脉冲穿孔(软穿刺)的方式,这使得激光能量在一个很小的区域过于集中,将非加工区域也烧焦,造成孔的变形,影响加工质量。这时我们应在加工程序中将脉冲穿孔(软穿刺)方式改为爆破穿孔(普通穿刺)方式,加以解决。而对于较小功率的激光切割机则恰好相反,在小孔加工时应采取脉冲穿孔的方式才能取得较好的表面光洁度。

This is because the machine (only for high power laser cutting machine) does not take the blasting method in the processing of perforation holes, but with the pulse perforation (soft puncture) way, which makes the laser energy in a small area is too concentrated, the non manufacturing area also burned, caused by hole deformation, influence the quality of products. At this time, we should be in the process of the pulse perforation (soft puncture) to change the way of blasting perforation (ordinary puncture), to solve. For small power laser cutting machine is just the opposite, in the small hole processing should be taken in the way of pulse perforation can get better surface finish.
