摘要
This paper presents investigations on discharging mechanism in powder mixed EDM.By analyzing the inception, growth of electrical tree and the ignition of discharges in liquid filled gap,the whole discharging process is proposed.It is explored that the reason of modification of ignition behaves by adding fine particle powders of metal or semiconductor to the working liquid.
