【Abstract】 The mathematical model of balanceable inter-electrode gap in higher frequency group-pulse electrochemical machining is presented. Based on the model, the relationships between the balanceable inter-electrode gap and the electrode voltage, the feeding velocity of cathode and the pulse frequency of supply power are discussed. Simulation and experiment show: the balanceable inter-electrode gap linearly increases with the increase of the voltage, nonlinearly decreases with the increase of the feeding velocity; there is strict linear relationship between the balanceable inter-electrode gap and the pulse frequency. In addition, it is also shown that the original inter-electrode gap has no influence on the balanceable inter-electrode gap. These conclusions provide significant guidance to optimize the electrochemical machining processing.更多还原
