Abstract
A wire-electrical discharge machine infuses a processing liquid in a gap between a wire and a workpiece and processes the workpiece using predetermined processing parameters. The machine includes a processing parameter memory that stores processing parameters, a second memory that stores a relationship between nozzle height and processing energy, a processing energy determining unit that determines the processing energy, for example, during rough processing, based on the relationship, and a processing parameter changing unit that changes the processing parameters based on the processing energy. The workpiece is processed using the changed processing parameters. According to this construction, wire breakage can be prevented and the accuracy of the processed surface can be improved.
