| Research Abstract |
Electrically conductive PCD(EC-PCD), which was made up of the electrically conductive diamond particles, was applied to an electrode material for precise EDM of cemented carbide die. The machinability of EC-PCD by EDM was investigated in comparison with standard PCD. It was found that EC-PCD was machined at better surface finish compared that of standard PCD because the diamond particles in EC-PCD were flattened by electro discharge. In EDM of cemented carbide die, the EC-PCD electrode shows the extremely low wear compared with the existing Cu-W electrode. Furthermore, the increase of material removal rate and improvement of surface property compared with the standard electrode can be realized.
