为了提高曲面零件的熔覆质量,根据激光熔覆的工艺特性对曲面零件进行了路径规划。对熔覆实验设备进行了简单的介绍,建立曲面零件模型。根据模型提出一种基于切平面法的路径生成方法,并利用熔覆道搭接率来确定切平面间距离;通过分析有效加工离焦量来计算步长大小,得出轨迹上的插补点集,进而分析加工控制点,并用偏置法得到枪头的位置与姿态;通过熔覆加工工艺实验进行验证,得到表面质量良好的熔覆层,从而验证了轨迹规划方法的合理性。 In order to improve the cladding quality of curved parts, the curved parts are planned according to the characteristics of laser cladding. The cladding experiment equipment is introduced briefly, and the surface part model is established. According to the model, a path generation method based on the slice plane method is proposed, and the overlap rate of the cladding lanes is used to determine the distance between the cutting planes. The step size is calculated by analyzing the effective processing of the defocus amount, Then the position and attitude of the pipette tip were obtained by offsetting method. The cladding layer with good surface quality was verified by the cladding process experiment, which verified the rationality of the trajectory planning method.
