Zusammenfassung:In order to solve the problem of an electrode guide interfering with the surface of an inclined workpiece in which a hole is to be formed, in the present invention, when performing electrical discharge machining on a workpiece via an electrical discharge machine (100) that has an electrode holder (7) and an electrode guide (8), a workpiece model (321) and an electrode-guide model (323) are generated in advance, an interference-start position at which the electrode-guide model (323) starts interfering with the workpiece model (321) when said electrode-guide model (323) is moved towards the workpiece model (321) along an axis line (CLa) is calculated, and a position obtained by moving the electrode-guide model (323) a prescribed distance away from the workpiece model (321), starting at the interference-start position, is set as an electrode-guide position. With the electrode guide (8) positioned at said electrode-guide position, the electrode holder (7) is moved downwards in order to move an electrode (10) downwards toward the workpiece surface, and electrical discharge machining is performed on the workpiece.
