Abstract: Aviation integral impeller is a typical complex high-precision parts, impeller's blade channel spacing is small. Leaf distortion is large and complex geometric structure which caused great difficulties for processing. In this paper, the DMU60 five axis machine tool is used to process the aviation integral impeller. The geometric simulation model of NC machining is built in the VERICUT software. It can effectively check the collision between the tool and fixture, the spindle and the working table, etc. In addition, the numerical control program is optimized by VERICUT optimization module, which can improve the machining efficiency and reduce the wear of machine tool and tool.
