Abstract:The structure of closed impeller is complex.The layering side milling method and the fixed milling method are usually used for rough machining.Through the fiveaxis machining technology，according to the tooling axis optimization technology research，the closed impeller channels are rough machined with fixedaxis highspeed milling method，and the fiveaxis machining of the axial closedtype impeller is completed with high efficiency.

Keywords:closed impeller；fiveaxis machining；fixed axis rough machining
