Background

The wire cutting refers to wire cut electrical discharge machining, and comprises three types, namely a high-speed reciprocating wire-moving electrical discharge machining, a low-speed unidirectional wire-moving electrical discharge machining and a vertical self-rotating electrical discharge machining, wherein the basic physical principle of the wire cutting is that free positive ions and electrons are accumulated in a field to quickly form an ionized conductive channel. At this stage, a current is established between the plates. Resulting in numerous collisions between the particles, forming a plasma and rapidly rising to a high temperature of 8000 to 12000 c, momentarily melting some of the material on the surfaces of the two conductors, while a bubble is formed due to the evaporation of the electrodes and the dielectric liquid and its pressure rises regularly up to very high levels. The current is then interrupted and the temperature suddenly drops, causing the bubbles to implode, creating a motive force that throws the dissolved material out of the crater, and the corroded material recondenses into small spheres in the dielectric fluid and is drained away by the dielectric fluid.
