Abstract
To improve the overall efficiency of impeller CNC machining,a centrifugal impeller with splitter blades was selected as the research object.On a five-axis CNC milling machine,a dedicated blank,fixture,and cutting tools were designed.Based on the 3D UG model of the impeller,QJCAM software was employed to optimize the toolpath programming for roughing,semi-finishing,and finishing.NC code post-processing was performed using UG Post Builder,and the feasibility of the efficiency improvement scheme was verified through simulation on the VERICUT machine tool.The results show that the optimized fixture,cutting tools,and cutting parameters reduced the overall machining lead time of the centrifugal impeller with splitter blades by 84%..Moreover,the optimized cutting tools exhibited extended tool life,enabling stable and efficient machining of impellers and blisks.This study provides technical support for the machining strategy of complex impeller components.关键词
