The wire cutting machine tool is formed by adding a machine tool to a wire cutting power supply control device, and the electric discharge machining is a machining pulse formed by combining high-voltage pulses and low-voltage pulses, and is divided into two stages of pulse width (ON) and pulse stop (OFF) according to time, wherein the stage of applying high voltage during machining is called an ON stage, and the stage of applying low voltage or turning OFF is called an OFF stage. In the ON stage, when the voltage of the gap is sufficiently small, the dielectric characteristics of the dielectric liquid between the gaps are destroyed, and then discharge occurs, and the high temperature and high pressure generated by the electric discharge machining evaporate or melt the workpiece material so as to achieve the purpose of cutting the workpiece material. In the process, high voltage, high current and high temperature are generated, if an operator does not notice that the parts such as fingers, palms and arms are easy to be in dangerous areas, electric shock and scalding risks are easy to occur, and personal safety accidents are caused. For example, patent document publication No. CN108526629a discloses a three-dimensional numerical control wire-cut electric discharge machine including a liquid tank and a table, a wire winding drum is installed at one end of a cross beam, the wire winding drum houses a resistance wire, and the resistance wire performs a cutting operation. If the operator does not pay attention to the region of the resistance wire where the hand is inserted inside the machine tool when the machine tool performs the cutting operation, dangerous accidents are easily caused.
