传统激光切割方法采用CO_2激光切割,对切口的角度和切割深度控制较差,并且不能实现切割轨迹自动纠偏。提出构建一种基于B样条曲线和高斯分布的激光切割轨迹自动化控制模型,首先拟合激光切割轨迹曲线,通过不断调整激光功率和光束移动速度参数,精确地计算激光切割角度和深度,并能够实现切割轨迹自动纠正偏移,实现激光切割轨迹的自动化控制。试验证明文章提出的方法能够有效地实现激光切割轨迹的自动化控制,并且在切割效率和精准度方面相比传统方法具有较大优势。
The traditional laser cutting method using CO2 laser cutting, incision angle and cutting depth control is poor, and can not be achieved automatically cutting trajectory correction. A control model of laser cutting trajectory based on B-spline curve and Gaussian distribution is proposed. Firstly, the laser cutting trajectory curve is fitted and the laser cutting angle and depth can be accurately calculated by continuously adjusting laser power and beam moving speed parameters Realize the cutting trajectory automatically correct the offset, to achieve automatic laser cutting trajectory control. The experiment proves that the method proposed in this paper can realize the automatic control of laser cutting trajectory effectively and has more advantages than traditional methods in cutting efficiency and precision.
