Application of foil electrodes for electro-erosion edge honing of complex-shaped carbide inserts

Electro-erosion honing is a novel process that exploits the undesirable but inevitable phenomenon of localized electrode wear in sink electrical discharge machining that rapidly rounds off sharp edges, for the edge honing of cutting tools. The process essentially entails the sinking of a sharp edge of a cutting tool into a counterface of an appropriate material to generate the round edge geometry. This paper proposes the innovative application …
