摘　　要：叶轮广泛应用于航空、航天和汽车等领域。然而由于其复杂的结构和较高的精度要求,长期以来制造工艺的选择一直是制造该类产品的难题。基于某型号叶轮模型的结构特点,对其制造工艺进行研究。首先对叶轮车削工艺方案与铣削工艺参数进行分析;其次对叶轮的加工轨迹与数控原理进行分析;然后结合UG数控编程模块对叶轮加工程序进行分析与编制;最后,结合加工平台与加工信息对叶轮进行实际加工。经检测验证,按新工艺加工的叶轮满足产品的设计与精度要求。实践证明了所设计的制造工艺的正确性与可行性;提升了加工正确率、效率与精度;研究结果对相似零件加工具有参考价值。Impeller is widely used in aviation, aerospace, automotive and other fields. However, due to its complex structure and high precision requirements, the choice of manufacturing process has been a difficult problem in the manufacture of this kind of products for a long time. Based on the structural characteristics of a certain type of impeller model, the manufacturing process was studied. Firstly, the impeller turning process scheme and milling process parameters were analyzed;next, the machining trajectory and numerical control principle of impeller were analyzed;and then the impeller machining program was analyzed and compiled in combination with UG NC programming module;finally, the impeller was processed in combination with machining platform and processing information. After testing and verification, the impeller processed by the new technology has met the requirements of product design and precision. The correctness and feasibility of the designed manufacturing process are verified by practice;and the accuracy, efficiency and precision of the machining are improved. The research results have reference value for similar parts processing.
