Principle of Spark Machine:
In the realm of Electrical Discharge Machining (EDM), the tool electrode and the workpiece are strategically connected to opposite poles of the pulse power supply. Immersed in working fluid or with fluid filled into the discharge gap, when the gap between these two electrodes achieves a specific distance, the applied pulse voltage overcomes the working fluid's resistance, thereby initiating a spark discharge.
During the brief discharge moment, a phenomenal concentration of heat energy occurs within the micro-channel, reaching temperatures over 10,000 degrees Celsius, alongside rapid pressure fluctuations. This immense energy leads to localized melting, vaporization, and expulsion of metal material into the working fluid. The expelled material quickly condenses into solid metal particles and is carried away by the working liquid, leaving a tiny pitting mark on the workpiece surface. The process halts momentarily as the working fluid restores its insulating state between the electrodes.
Subsequent pulse voltages trigger further discharges at nearby points between the electrodes, repetitively generating spark discharges. Each pulse discharge erodes a minuscule amount of metal, but given the high frequency of thousands of pulses per second, substantial metal removal is achieved, ensuring significant productivity.
Maintaining a consistent discharge gap between the tool electrode and workpiece, the metal erosion of the workpiece proceeds as the tool electrode advances towards it. Eventually, the machined shape replicates that of the tool electrode. By changing the tool electrode's shape and its relative motion to the workpiece, complex profiles are meticulously crafted. Materials with high electrical conductivity, melting points, and ease of processing, such as copper, graphite, copper-tungsten alloy, and molybdenum, are typically used for tool electrodes. Although the tool electrode wears out, it is minimal compared to the workpiece metal corrosion and often considered negligible.
Acting as the discharge medium, the working liquid is crucial for cooling and chip removal during the machining process. Preferred working liquids include low-viscosity, high flash point, and stable performance mediums such as kerosene, deionized water, and emulsion. EDM machines operate on self-excited discharge principles: the spark discharge between the electrodes initiates with a high voltage, breaking down the medium as the electrodes near each other, sparking the discharge. The discharge leads to a sharp drop in resistance and voltage. The spark channel must extinguish quickly (within 10-7 to 10-3 seconds) to maintain the 'cold pole' characteristic, ensuring the channel energy affects only a tiny area, causing localized erosion of the electrode. This erosion-based material removal technique is known as EDM.
