Abstract

The invention relates to a method for electrical discharge machining of electrically non-conductive material in which a layer of an electrically conductive substance is applied as an auxiliary electrode on the electrically non-conductive material. Said method is characterized in that the electrically conductive substance is chemically converted by oxidative heat treatment after electrical discharge machining.
