摘　　要：In order to develop green manufacturing and microfabrication,an innovative electrochemical machining method was introduced,that is the electrochemical machining(ECM)technology in ultra-pure water.The relative relationship of water dissociation and current density under the function of strong acid cation exchange membrane was studied,and the mechanism of electrochemical machining in ultra-pure water was also explored.On the basis of theoretical analysis,the significance of two turning points of the voltage-current density characteristic curve was presented.As the result of water dissociation and machining experiments,the factors affecting current density were determined.In order to develop green manufacturing and microfabrication, an innovative electrochemical machining method was introduced, that is the electrochemical machining （ECM） technology in ultra-pure water.

On the basis of theoretical analysis, the significance of two turning points of the voltage-current density characteristic curve was presented.
