[0002] An electric discharge machine tool, also known as a numerical control electric discharge machine tool, electric discharge machine, spark machine, etc., is an electro - machining equipment. Its basic physical principle is that free positive ions and electrons accumulate in the field and quickly form an ionized conductive channel. At this stage, a current is formed between the two plates, causing countless collisions between particles, forming a plasma region, and quickly rising to a high temperature of 8000 to 12000 degrees. Some materials on the surfaces of the two conductors are instantly melted. At the same time, due to the vaporization of the electrode and the dielectric fluid, a bubble is formed, and its pressure regularly rises until it is very high. Then the current is interrupted, the temperature suddenly drops, causing an internal explosion in the bubble. The generated power throws the melted material out of the crater, and the corroded material re - condenses into small spheres in the dielectric fluid and is drained away by the dielectric fluid. Then, through the monitoring and control of NC control, the servo mechanism executes to make this discharge phenomenon uniform, so as to achieve the processing of the workpiece to make it a product with the required size and shape accuracy.
