放电电流的脉冲宽度对电火花加工过程中阳极和阴极的去除量有很大影响。本研究的目的是找出这种现象的原因。首先通过测量电极温升和电极去除量，得到单次放电过程中阳极和阴极的能量分布。研究了阳极表面碳附着对阳极去除量的影响。结果表明，脉冲宽度对能量分布的影响较小，阳极的能量大于阴极。此外，从实验结果得出结论，在电火花加工过程中，阳极和阴极之间的去除量的差异主要是由碳的粘附，而不是由能量分配。
The pulse duration of discharge current greatly influences the removal amount of anode and cathode in EDM process. The purpose of this research is to find out the reason for such a phenomenon. At first, the energy distributed into anode and cathode in the case of the single discharge process is obtained by means of measuring the temperature rise and removal amount of electrodes. Then the influence of the carbon adhesion onto the anode surface on the anode removal amount is investigated. It is found that the energy distributed into the anode is more than that into the cathode, and the influence of pulse duration on the energy distribution is small. Besides, it is concluded from the experimental results that the removal amount difference between anode and cathode in the EDM process is mainly caused by carbon adhesion, not by the energy distribution.
