摘　　要：以双NURBS曲线获得的直纹面广泛存在于各行业复杂零件中,如何实现复杂直纹面的增材制造一直是增材制造领域中极为关心的问题。以双NURBS曲线描述叶片模型,进一步获得直纹面,采用优化工艺参数,以GMAW方法实现了叶轮叶片的增材制造,增材获得的叶片完整,成形良好,表明以GMAW工艺实现双NURBS曲线叶片增材制造是可行的。为叶片模型构建、复杂形状叶片的电弧增材制造提供了新方法,对复杂形状零件增材制造过程控制具有借鉴意义。Ruled surfaces obtained from dual NURBS curves are widely used in complex parts in various industries.How to realize additive manufacturing of complex ruled surfaces has always been a problem of great concern in the additive manufacturing field.The blade model was described by dual NURBS curves,and the ruled surface was further obtained.By optimizing the process parameters,the additive manufacturing of impeller blades was realized by GMAW method.The blades obtained by additive manufacturing are complete and well formed,which shows that it is feasible to realize the additive manufacturing of dual NURBS curve blades by GMAW process.This study provides a new method for blade model construction and GMAW additive manufacturing of complex shape blades,and has reference significance for additive manufacturing process control of complex shape parts.
