In order to find the origin of the quality problem accurately and quickly, confirm the quality of the related parts, combining with the thoughts of manufacturing execution system, this paper presented a quality tracing support system for production process of machining department in multi-varieties and small-batch environment, which can support quality data dynamic acquisition, quality problem positive and reverse tracing, quality problem analysis and handling. Then the architecture，function structure and running processes of the system were set up, and the three-dimensional model for production process of process quality constructed. Furthermore, the process quality analysis and handling technology of case based was studied. The system was successfully applied in a multi-varieties and small-batch manufacturer, and good results were obtained.
