Experimental Research on NC Electrochemical Machining of Passage between the Two Adjacent Blades of Integral Impeller

Abstract:

ntegral impeller geometries are complex and its material is also particularly difficult to machine, what makes conventional machining cannot process the integral impeller in the high quality, low cost way. The article study on the groove of the integral impeller is processed by the way of NC electrochemical machining. By orthogonal experiments, based on analyzing the factors such as cathode width, machining voltage, electrolyte pressure and spindle speed, and the optimal parameters was obtained. The test results show that using NC electrochemical machining of integral impeller has an irreplaceable superiority.
