| Research Abstract |
Although electrical discharge machining(EDM) of Sintered polycrystalline diamond(PCD) is possible, the removal rate is extremely low. We investigated the possibility to apply the Bi-polar Pulse for the EDMing of PCD. We confirmed that the removal rate of PCD using the bi-polar pulse is higher than using normal pulse(electrode positive or negative polarity). Moreover, the electrode wear ratio is also improved.
