Information is given on peculiarities of abnormal changes of the effective power in electrolytic dia- mond machining of cemented carbides with polycrystalline cathodes (EDMPC) having smooth working sur- faces. The dependence of Nef on the voltage across the electrodes and the “residual action” of voltage on the cemented carbides are shown. The abnormal variation of Nef is inadequate to that of the process current den- sity with increasing voltage across the electrodes. “Original” experimental data on the interrelation between U, i and Nef for different combinations of the variants of machining are given as oscillograms. Analysis of the interrelation between the process parameters in the main ranges of the IV characteristic suggests that the EDMPS of cemented carbides should be carried out at U = 15 V.
