摘要：
Failure Mode, Effects and Criticality Analysis (FMECA) of remanufactured machine tools is one of the key issues for improving their quality and reliability. According to the characteristics of remanufactured machine tools and the basic principle of FMECA, the method of failure mode analysis for remanufactured machine tools in service is proposed, with the FMECA procedure being expounded in detail. In addition, failure criticality of each failure mode for remanufactured machine tools is analyzed by risk priority number (RPN) method. Finally, the method is demonstrated in a case study of remanufactured YX3120 gear hobbing machine. The results from the case study are discussed and conclusions are drawn.
