摘　　要：本文从微观失效特征和仿真模拟两方面对实际加工过程中35°数控精车刀片的失效原因进行了综合分析。结果表明:粘着磨损和微崩刃是35°数控精车刀片的主要失效特征,失效原因可能是切削速度过快。The failure causes of 35° CNC finishing inserts in the actual machining process are comprehensively analyzed from the aspects of microscopic failure characteristics and simulation. The results show that the main failure mechanisms for 35° CNC finishing inserts are adhesive wear and micro-chipping blade, and the failure reason may be caused by too fast cutting speed.
