摘要
在微孔精密加工工艺中,常规的电机运动轨迹已经很难满足产品的工艺标准。通过运动控制系统搭建,采用直线缓冲与圆弧过渡两种主要方式,改变激光加工轨迹,以减少电机速度较慢时烧蚀严重所造成的孔径不规则现象,并克服了首脉冲带来的热影响。实验证明,该方法有效的改善了激光加工的工艺效果。
In micro-holes precision machining process,the conventional motor motion path could hardly meet the technology standards of products. By establishing motion control system,two main ways of linear buffer and arc transition are used to change the laser machining path,so as to reduce the irregular aperture caused by serious ablation when the motor speed is slow,and overcome the thermal effect caused by the first pulse. Experiments show that this method can effectively improve the technological effect of laser machining.
