摘　　要：文章通过对激光熔覆过程中机器人在尖角处过渡时产生的误差进行分析,提出了机器人在尖角处匀速过渡的插补算法。通过在尖角外围添加补偿点并精确控制激光开/关设计了机器人插补流程,利用C#.NET编程语言编写机器人插补软件,并采用OpenTK实现插补运算后的数据可视化。仿真和实验验证机器人路径的可行性,并成功熔覆出含有60°尖角的薄壁件。研究结果为激光熔覆含有尖角特征的薄壁件提供了理论指导和实验依据。The error resulting from robot＇s transition at sharp corner during the laser cladding process was analyzed, and an interpolation algorithm with the characteristic of uniform transition at closed angle for laser cladding robot was introduced. The interpolation process was demonstrated by using the methods of adding compensation points at the sharp corner and controlling the laser on/off precisely, and the algorithm software was programmed by C~. NET programming language. To achieve the da- ta visualization, the corresponding display interface in OpenTK was proposed： The simulation and ex perimental results verified the feasibility of the robot path, and a thin-walled part with a sharp corner of 60° was successfully clad. The study can provide theoretical guidance and experimental basis for laser cladding on thin-walled part with angle characteristic.
