Disclosed is a method for designing an electrode for electric discharge machining of a workpiece, based on a reverse shape to a shape of the workpiece by use of a CAD system, which comprises the steps of obtaining a first reverse solid having a reverse shape to a shape of the workpiece, from a solid of the workpiece, uniformly offsetting an entire surface of the first reverse solid by a thickness necessary for a discharge gap to obtain a second reverse solid and subjecting the second reverse solid and one or more swept reverse solids created by copying the second reverse solid while allowing a sweep movement by a small distance in a direction conforming to a rocking motion, to a logical product (AND) operation to obtain a shape of an electrode as a third reverse solid.

The present invention provides a die design support method and system capable of reducing the time-period required for a die design, allowing an unskilled die engineer to perform a die design without difficulties, and coping with a product design change in a short time-period. A standard die design procedure is stored as “master die data” in advance using a function of a CAD system or the like. When a product design data is entered, the design procedure is automatically executed to the design data in accordance with the stored master die data. Preferably, the entire master die data is divided into a plurality of processes, such as a process of creating a scaling model, and a process of creating a parting model.
