| 中文摘要: |
| 研究电极加工时间对电火花加工效率的影响规律可以为控制电极加工时间来提高电火花加工效率提供重要理论依据．首先通过实验检测不同电极加工时间对应的有效放电频率,发现在带抬刀的电火花加工中,加工效率随电极加工时间的增加而先增加后降低．随后通过观察放电过程中加工间隙内气泡和加工屑的运动,发现底面间隙内加工屑浓度随电极加工时间的增长而增加．在此基础上,证明了加工效率随电极加工时间的变化规律具有确定性． |

| The research on the influence of electrode machining time on electrical discharge machining (EDM) efficiency can provide important theoretical basis for controlling the electrode machining time on the purpose of improving EDM efficiency. Firstly, the machining efficiency is found to increase firstly and then decrease along with the electrode machining time through measuring the effective discharge frequency under different electrode machining time in the electrical discharge machining with electrode jump. Then, through observing the movement of bubbles and debris in gap, it is found that the debris concentration in the bottom gap increases along with the electrode machining time. Based on such observations, the relationship between the machining efficiency and electrode machining time is proved to be deterministic. |
