Simulation of Particles Movement in Powder Mixed EDM

Abstract:

Article Preview

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. Concentration and distribution of particles 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.
