Properties of Electro Discharge Machining with a Spinning Disc Tool System

We have developed a spinning disc tool systemto test machining properties of such a tool to enhance theElectro Discharge Machining (EDM) process of hard anddifficult to machine materials. We performed experimentalmachining tests with this disc tool system. We havemeasured and explained effects, which affect the stability ofthis electro discharge machining process with use of thespinning disc tool technique. We found out this system mayspeed up material removal rate of the EDM process, but itsuse for micromachining is limited by the tool wear
