摘　　要：为了研究增减材复合制造技术在叶轮等工业零件加工制造中的应用,通过使用UG/NX软件建立模型并定义每个加工特征,同时编制了增材与三种减材的刀轨轨迹路径,并优化了切削参数。采用五轴激光沉积增材/高速减材复合制造设备进行了试验验证。结果表明,结合增材制造和减材制造的优势,显著提高了零件的表面质量、加工效率和综合性能。未进行面铣加工的叶片表面粗糙,经过面铣和型腔铣削加工后的叶片表面光洁度显著提高,内部型腔的表面质量亦明显改善。增减材复合加工不仅提高了零件的表面质量,还有效提升了加工效率和材料利用率,降低了生产成本。证明了增减材复合加工技术在复杂零件制造中的巨大潜力,为高质量工业零件的生产提供了可靠的技术途径,为增减材复合制造技术领域提供参考。In order to study the application of additive and subtraction composite manufacturing technology in the machining of industrial parts such as impellers,UG/NX software was used to model and define each machining feature,and the tool track paths of additive and three kinds of subtraction were compiled,and the cutting parameters were optimized.A five-axis laser deposition additive/high speed reduction composite manufacturing equipment was used for experimental verification.The results show that the surface quality,processing efficiency and overall performance of the parts are significantly improved by combining the advantages of additive manufacturing and subtractive manufacturing.The surface of the blade without face milling is rough,the surface finish of the blade after face milling and cavity milling is significantly improved,and the surface quality of the inner cavity is also significantly improved.Additive and subtraction composite processing not only improves the surface quality of parts,but also effectively improves the processing efficiency and material utilization rate,and reduces the production cost.It proves the great potential of additive and subtractive composite processing technology in complex parts manufacturing,provides a reliable technical way for the production of high quality industrial parts,and provides a certain reference value for additive and subtractive composite manufacturing technology.
