Abstract
A method for fabricating electrical discharge machining electrodes includes forming a thin electrode shell by compression molding a mixture of carbon particles and an organic binder. The electrode shell is then thermally processed to graphitize the organic binder and carbon producing an electrode with the structural integrity needed so as to be useful in electrical discharge machining.
