以水轮机叶片维修加工为例,引入针对曲面拟合的拟合优度综合指数G,对逆向工程扫描数据的平滑处理结果进行评价,采用需要再加工工件的模型与理想工件模型在同一参考系中进行布尔运算,产生切削加工量的方法编制数控加工工艺,从而使大型复杂工件现场再制造技术中对于未知零件表面测量数据的平滑处理、造型和数控加工工艺问题,得到较好解决.%With maintenance processing of turbine blade as an example, through the introduction of goodness-of-fit index G fitting results were evaluated, the workpiece and the ideal model for contrast produced cutting amount, the problem of the large and complex field of remanufacturing technology for unknown parts surface measuring data fitting, modeling and NC machining, get better solution.
