目的 研究激光模切加工过程中激光束扫描运动控制算法。 方法 首先通过编写激光模切扫描的相关控制程序， 自动读取矢量模切图形并生成相应的 G代码， 然后对模切过程进行动画预览， 如果发现问题就对G代码进行相应的修改， 从而自动生成完善的下位机控制程序， 最后搭建实验平台进行验证。 结果 激光模切扫描算法能够准确地控制激光束的模切轨迹， 最大加工误差为± 0.05 mm， 激光模切效果比较理想。 结论 基于该激光模切扫描算法的控制系统， 能够对生产线上移动的印刷品进行完全数字化模切加工。

Objective To study the scanning algorithm of laser die-cutting. Methods Through writing the control program of laser die-cutting, the vector graphics could be read and the G code could be generated automatically, and then the preview of cutting process could be displayed in animation form. If any problem was found during the preview, the G code could be modified accordingly. Accordingly, a more perfect lower machine control program would be generated automatically. At last, a experimental device was set up to verify this scanning algorithm. Results The scanning algorithm could control the die-cutting trajectory of the laser beam, the maximal processing error was ±0.05 mm, and the results of laser die-cutting were relatively ideal. Conclusion The laser die-cutting control system based on this scanning algorithm could realize fully digital die-cutting for the moving printed matters in production line.
