| 摘 要： | 电火花加工的放电蚀除过程是在极短时间内和极微小空间内发生的,导致用观测和理论分析的方法进行研究都极其困难,因此其放电蚀除机理至今仍未能被明确的解释.论文应用分子动力学方法对微细电火花加工的放电蚀除过程和熔融区的形成及形状等进行了模拟研究,该研究基于放电通道变化的热源模型,并与放电通道恒定情况下的模拟结果进行了对比,证明...

| Abstract: | Electrical discharge phenomena in EDM occur in a very short time period and in a very narrow space,thus making both observation and theoretical analysis extremely difficult.For this reason,the material removal mechanism in EDM has not yet to be understood clearly.In this paper,micro-EDM discharge removal process,the formation and shape of electrode molten zone was analyzed based on discharge channel changing model using Molecular Dynamics(MD).It can be concluded that the discharge channel changing model is ... |
