【摘要】 为消除叶片在加工过程中的产生的振颤刀痕,采用有限元分析方法仿真了叶片接触加工时的振动模态,分析了加工过程中工件的动态响应,在此基础上改变叶片的毛坯结构和工艺规程,将加工中刀具与工件颤振产生的误差降为最低,从而提高叶片表面加工的质量。更多还原

【Abstract】 To eliminate the vibration of blade during machining, the finite element analysis method is used to simulate the vibration modal of the blade contact machining and analyze the dynamic response of the artifacts in the machining course. On this basis it is to alter the rough structure and the production instruction of the blade, the chatter error of the cutter and the blade in machining is reduced to a minimum, so as to improve the quality of blade surface machining.更多还原
