在自制的单脉冲放电实验装置上进行了不同材料、不同参数的单脉冲放电实验,并采用数字存储示波器记录下不同情况下的单脉冲放电的电流电压波形数据,经过分析认为,虽然聚晶金刚石电火花加工的放电波形与普通电火花加工非常类似,但在击穿电压、火花维持电压及短路特征波形等方面具有自己的鲜明特征。
Single-pulse discharge test device made of different materials, different parameters of the single-pulse discharge test and the use of digital storage oscilloscope recording single-pulse discharge under different current and voltage waveform data, after analysis, although the polycrystalline diamond EDM discharge waveform and EDM are very similar, but in the breakdown voltage, spark maintenance voltage and short-circuit characteristics of the waveform has its own distinctive features.
