In this study, it was clarified that discharge locations can be controlled by locally superimposing high electric fields. On the basis of this principle, two methods for improving the controllability of discharge locations in wire electrical discharge machining (WEDM) were proposed: 1) increasing the local high electric field by increasing the superimposing voltage, and 2) increasing the discharge probability by successive superimposition in each discharge cycle. The experimental results showed that discharge locations in conventional dry WEDM can be dispersed uniformly over the workpiece surface, and the discharge can be successfully moved to the vicinity of the point where high voltage is applied.
