An electrical discharge machining apparatus includes a simulator. The simulator calculates machining information relating to machining shape at each of several simulated machining depths, when the electrode is moved into a workpiece, until an input machining depth is obtained, based on the shape of the electrode input, the shape of the workpiece, and the machining depth of the workpiece, and determines a shape obtained by subtracting the machining shape from the shape of the workpiece, as a new shape of the workpiece, at each simulated machining depth.
