摘要: 激光功率对切割质量具有重要的影响,功率过大容易产生过烧现象。为了保证切割质量,研究了激光功率与切割速度的关系,基于可编程多轴运动控制器提出了激光功率实时控制的方法,使用开放性编写应用程序进行串口通信调整功率的方式实现激光功率的实时控制。采用这种方法进行激光切割试验,当激光功率能够随切割速度实时变化时,可以避免烧角现象。结果表明,此方法可以有效地提高切割质量,并且保证了激光切割的效率。

Abstract: Laser power has important influence on the cutting quality,and the burning defect is easy to happen if the laser power is too high.In order to guarantee the cutting quality,a real-time power control method based on programmable multiple axes controller was presented to study the relationship between laser power and cutting speed.The analysis of laser cutting test shows that burning defect can be avoided when laser power can change with the cutting speed, the cutting quality can be improved effectively by this method,and efficiency of laser cutting is guaranteed.
