激光切割系统功率实时控制研究

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。

Research on real-time power control of laser cutting system based on PMAC

Laser power has important influences on cutting quality, and it is easy to produce burning defect when laser power is too high. A real-time power control method based on PMAC is presented by studying 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 depending on cutting speed, cutting quality can be improved effectively by this method, and efficiency of laser cutting is guaranteed.
