高频群脉冲电解加工的极间平衡间隙

给出了脉冲电解加工极间平衡间隙的数学模型，并据此讨论了高频群脉冲电解加工极间电压、阴极进给速度和电源脉冲频率与平衡加工间隙(极限平衡间隙)间的关系。模拟和实验表明：极限平衡间隙随极间电压升高而升高，它们呈近似的线性关系；随阴极进给速度增加，极间平衡间隙非线性地降低；而极限平衡间隙与脉冲频率则呈严格的线性关系，即随频率增加平衡间隙线性减小。极限平衡间隙与初始加工间隙无关，即一定的阴极进给速度和极间电压对应的稳定平衡间隙是不变的。

The balanceable inter-electrode gap in higher frequency group-pulse electrochemical machining

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.
