摘　　要：基于多通道放电原理,设计了旋转集束电极多通道烧蚀加工装置,并使用该装置进行多通道烧蚀加工工艺试验,研究了氧气压力、脉冲宽度和低压电流对材料去除率的影响。结果表明:氧气压力增高,材料去除率呈现先增大后不变的趋势;脉冲宽度增大,材料去除率先增大后减小,且脉冲宽度为250μs时的材料去除率最高,达到12 mm3/min;随着低压电流的增大,材料去除率呈现线性增大趋势。Based on the multi-channel discharge principle,a multi-channel ablation processing device for rotating bundling electrodes is designed.The device is used to test the multi-channel ablation process.The effects of oxygen pressure,pulse width and low-voltage current on the material removal rate are studied.The research shows that the higher the oxygen pressure,the higher the material removal rate is,and the larger the pulse width is,the larger the material removal rate is.The highest material removal rate is 12 mm3/min when the pulse width is 250μs.The material removal rate increases linearly with the increase of low voltage current.
