Abstract: To meet the needs of effective part process quality control and flexibility in manufacturing process, wireless network technology was introduced into manufacturing process. A manufacturing quality control mode based on wireless technology was put forward. Operation logic and physical implementation of this mode were described and analyzed in particular. As a core component for the mode mobility, quality control terminals were used for conducting real-time processing and analysis for part process quality and correlative node information in manufacturing process. Various quality control methods related to three kinds of production modes were discussed and analyzed deeply in the context of wireless applications. Based on above-mentioned studies, a machining error correlative analyzing method that combined the statistic process control chart with the correspondent working conditions was put forward. Finally, a prototype system for online e-quality control and error analysis was developed by using wireless network technologies. The methods have been proved by the result of system operation.
