A method of electric discharge machining using a wire electrode for cutting a workpiece into a commanded shape by producing an electric discharge between the workpiece and the wire electrode and moving the wire electrode relative to the workpiece along a commanded path. The method includes steps of previously storing, in a computer memory, sets of machining conditions which differ depending upon workpiece material and thickness, reading, at the time the workpiece is to be machined, a predetermined set of the machining conditions from the memory in response to a machining condition selection instruction in a machining program and performing electric discharge machining in accordance with the set of machining conditions read from the memory.
