为了提高激光再制造的质量和效率，结合逆向工程和激光再制造的特点，介绍了缺损工件的激光再制造路径规划。阐述了扫描缺损工件的表面以得到点云数据，采用逆向工程重构修复区三维形貌，再配以激光再制造工艺进行路径规划。加工控制点矢量算法为加工头姿态提供了一种行之有效的方法。

To increase the efficiency and accuracy of laser remanufacturing, a method of path planning with combining the characteristics of reverse engineering and laser remanufacturing is presented. The following aspects are contained: obtaining point clouds by scanning the surface of worn workpieces, reconstructing of repair area by reverse engineering, doing the path planning comparing with laser remanufacturing parameter. The calculation of laser processing head axis vector improves the direction and distance control accuracy of laser processing robot.
