Finite Element Analysis and Parameter Optimization for Mirror EDM without Mixed-Powder

Abstract:

By analytical and finite element analysis method, this paper analyzes the various factors on the impact of EDM surface roughness. Put forward in the process of EDM according to the coarse, medium and fine, step by step to change the order of the processing conditions, and in turn increase the momentum of the swinging electrode EDM mirror machining method. Analysis and calculate the feeding and machining allowance of each process conditions. Experiments show that in the mixed powder fluid, not replace the electrodes and processed work pieces of 45 # steel, surface roughness of work piece reached Ra0.02μm.
