Electrode Material Effect on Electrical Discharge Machining PcBN Cutting Tool Processing

Abstract:

The electrode material is playing the very important role in the electrical discharge machining. Two kinds of electrode materials common used in EDM are compared and analyses similarities and differences in structure and physical characteristics. Combined with PcBN tool machining tests, from the electric discharge machining efficiency, electrode wear, tool surface quality, tool surface degenerating layer, machining results are in analysis and comparison, and then different electrode materials machining technics in electrical discharge machining process are summarized. Through the cutting tool electric discharge machining experiments, we can know that the graphite electrode easy to take shape, suits in the complex edge's cutting tool electric discharge machining, under the same electric discharge machining parameter condition, its processing efficiency must be higher than the copper electrode, but the electrode loses, the cutting tool surface quality and affect layer thickness are to be worse than the copper electrode.
