Influence on Discharge of Particle Concentration and Distribution in Powder Mized EDM
The particles dispersed in gap can increase the discharge stability and reduce discharge energy density in powder mixed EDM, which effectively improve the surface quality of machined workpieces. In order to study the mechanism of powder mixed EDM process, particles concentration and distribution computed by finite element methods in working conditions were simulated and corresponding experiments were done. The activities of particles in the discharge process were analyzed by experiments and theories. The results show particles have group effect in the gap and that the effect closely associates with particles concentration.
