Summary:In unconventional material removal process powder mixed electrical discharge machining (PMEDM) is the new development of machining features such as material removal rate, tool wear ratio and surface roughness, when the profitable powder additives in a liquefied and gaseous dielectric fluid are supplied in the procedure. By electrolysis formed the pre-breakdown stage in water is considered by the creation of several little hydrogen bubbles. In a gasiform medium the streamers flow very much easily and at that moment these bubbles may be able the infringement method. In oil medium, no bubbles are detected. Therefore, in the space of tools and job some elements augmented cause of the breakdown progression in oil.
