    摘要: 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.
