摘　　要：针对复杂产品的加工过程质量控制问题,提出了一种面向多工序制造过程的e-质量控制模式,给出了其功能体系结构。该模式以构建面向加工设备的工序质量e-化模型为基础,综合运用了统计过程控制、设备状态诊断、状态空间建模和数模比对等理论和技术,实现的方法是建立e-质量控制系统。详细分析了制造过程中关键控制参数的选取、传感网络的构建、面向设备前端工序质量e-化模型的建立、基于零件加工特征的多工序过程质量控制模式的集成等关键使能技术,并给出了基于浏览器/服务器结构的e-质量控制系统的实现模式,为实现复杂零件的高精度、数字化加工提供了一条新途径。To solve problems concerning the process quality control of complex products, a quality control mode oriented to multistage machining processes, corresponding functional modules and framework were all put forward. This mode dealt mainly with constructing and running an e-quality control system, integrated several enabling technologies such as Statistical Process Control （SPC）, equipment status diagnosis technology, state space modeling and mathematical model comparison. Furthermore, some of the key enabling technologies were studied in detail, including determining key control parameters, constructing sensor network, modeling e-quality model, and establishing feature-driven integrated quality control model based on multistage machining processes. They were used under the Browser/Server （B/S） architecture to perform the functions of e-quality control. Finally, the feasibility of proposed method was verified preliminarily with a developed prototype system.
