摘　　要：针对复杂零件制造过程,提出基于多源多工序的误差传递控制方法。采用复杂网络建模理论构建加工误差传递网络,通过分析其网络特性,发掘加工工序中的关键控制工序及影响加工质量的因素。对关键控制工序进行工序流波动分析,从系统的角度衡量多个工序的波动变化,并运用统计过程控制图对关键控制工序加工特征进行质量控制,以保证其加工质量和加工过程平稳,进一步采用工序波动轨迹图及多工序能力指数分析,对工序流进行加工质量波动分析与工序能力的量化评价。以某轴流风机动叶机加工过程为研究对象,对所提误差传递控制方法进行了验证。Aiming at the manufacturing process of complex parts,an error propagation control method was proposed based on Multistage Machining Processes（MMPs）.The modeling complex network theory was used to construct the Machining Error Propagation Network（MEPN）.By analyzing the characteristics of MEPN,the key control processes and the influencing factors for the machining quality were obtained.The key control processes were analyzed by process fluctuation and the changes of multiple process fluctuation was measured from system.To ensure the processing quality and stability,the Statistical Process Control（SPC） charts were used to monitor the key processes.Furthermore,by using Process Variation Trajectory Chart（PVTC） and process capability index,the fluctuation analysis of machining quality and quantity evaluation of process capability were obtained.The axial-flow blade was taken as research subject to verify the proposed method.
