Abstract

Abstract:

Powder mixed electrical discharge machining (PMEDM), using kerosene with suspended powder as the dielectric fluid, can work steadily at very low pulse energy with satisfying results and the powder particles is believed to play an important role in discharging. Considering the electric field aberration in the interelectrode gap caused by the particles, the polarization of electric field is calculated and the influence of particle on electrical tree is analyzed in this paper.
