Electrospark machining method for workpiece, involves frustrating variations of machining gap width by permanent adjustment internal loop, which controls average machining power based on law, where loop does not induce any movement of axles

摘要

The method involves positioning a tool (1) based on axes relative to a workpiece (2), where spark discharges are separated relative to each other by a dead time (TS) in which no electrical voltage is presented at a machining gap between the tool and the workpiece. A width of the gap is measured in real time. Variations of the width are frustrated by a permanent adjustment internal loop, which controls an average machining power based on a continuous law, where the time, output or input value and the width depends on law. The loop does not induce any movement of axles (3, 4, 15).
