摘要
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。
Laser cutting is adopted in the traditional laser cutting,which has poor control in angle and depth of cut,and can not realize automatic trajectory correction. In this paper,we develop a laser cutting trajectory automatic control model based on calculus and Gaussian distribution. Through constantly adjustments of laser power and beams＇ moving velocity parameters to accurately calculate the laser cutting angle and depth,and to realize the automatically correction of the cutting track. Finally meet automatic control of the laser cutting trajectory. Experiments show that the proposed method can effectively achieve the automatic control of laser cutting trajectory,and has advantages in cutting efficiency and accuracy.
