Abstract: To solve the complex control problem of multiple key quality characteristics in product manufacturing process, a multiple key quality characteristics optimization model for manufacturing process was established. Various influencing factors for multiple quality characteristics were extracted by using Quality Function Deployment(QFD)technology, and the fluctuation rate of key quality characteristics was defined. Based on the analysis of interrelationships among manufacturing factors, the quota relationship between the multiple key quality characteristics and the influencing factors was established. Furthermore, the valid target values of manufacturing factors were identified with the constraint of Quality Control(QC)cost to minimize the total quality fluctuation in manufacturing process. Finally, a case study on key quality characteristics optimization of gear hobbing processing was provided to illustrate the effectiveness and feasibility of the model.
