报告人：Jionghua (Judy) Jin (金炯华)Professor, Director of Manufacturing ProgramIndustrial & Operations EngineeringDepartment University of Michigan
(Abstract)Existing research on cyclic profile monitoring is limited to between-cycle detection made for each finished part based on its entire cycle of signals. In manufacturing processes with critical part quality and high cost, however, process changes require detection before the part is produced so that within-cycle adjustments can be triggered. This paper develops a wavelet-based profile monitoring method that is capable of making within-cycle decisions and guiding real-time process adjustments. The proposed within-cycle monitoring technique integrates real-time monitoring and within-cycle control opportunity for defect prevention. The optimal decision time is determined through the formulation of an optimization problem. The effectiveness of the proposed method is validated and demonstrated by simulations and a case study in an ultrasonic welding process.
