Quality Control System for Short-Runs Based on Machining Error Propagation Network

To solve problems concerning the process quality control of short-runs, a framework of quality control system for short-runs is put forward, and corresponding functional modules and working mechanism are also studied. The system is established on the foundation of machining error propagation network (MEPN), and quality control and improvement can be implemented by analyzing the dynamic characteristics of MEPN. In addition, some key enabling technologies, including MEPN modeling and analysis, error source diagnosis based on fuzzy inference as well as error coordination and optimization, were discussed in detail.
