碩士 === 國立勤益科技大學 === 資訊管理系 === 107 === In order to prevent the failure of manufacturing procedures, the mechanical industry needs to invest in the cost and time of improvement measures. How to effectively solve the failure scheme and select optimized improvement measures, the method has to improve the process effectively. This study explores the failure mode factors of computer numerical control planer to establish the failure items by system thinking, analyze the failure problems caused by the failure of the manufacturing system and the evaluation solutions. During the research, we will invite eight senior woodworking industry experts to investigate questionnaire interviews, explore the failure mode factors of CNC planer through interviews and review the related literature. The proposed method will establish research model structure and use Fuzzy Delphi Method to objectively select the key factors and indicators. Furthermore, this study explores the potential failure modes of the CNC computer by using failure mode and effect analysis method. Moreover, we will propose the corresponding improvement solutions to reduce the risk of failure for CNC planer machine. In the research, the method firstly analyzes the assembly process of CNC planer and explores the possible failures of causes in each procedure. From the results of the analysis, it shows that there are 36 potential failure problems in the computer assembly process. Similarly, we also analyze each failure mode by FMEA and obtain the risk priority number. Finally, this study proposes improvement strategies and recommendations to reduce the risk of failure, and takes appropriate measures based on the risk priority number and related schemes. Consequently, the proposed method can reduce the failure risk of the assembly process and promote the reliability of CNC planer.
