Fundamental Principles of Spark Machining:
In the sophisticated domain of Electrical Discharge Machining (EDM), the tool electrode and workpiece are ingeniously attached to opposite poles of a pulse power supply. Submerged in a working fluid, or with fluid filling the discharge gap, when the gap between these electrodes reaches an optimal distance, the applied pulse voltage surpasses the resistance of the working fluid, thereby triggering a spark discharge.
During the fleeting discharge moment, an immense amount of heat energy converges within the micro-channel, escalating to temperatures beyond 10,000 degrees Celsius, accompanied by swift pressure variations. This intense energy induces localized melting, vaporization, and expulsion of metal material into the working fluid. The expelled material rapidly solidifies into metal particles, which are then efficiently carried away by the working liquid, leaving a minuscule pitting mark on the workpiece surface. The process temporarily halts as the working fluid rejuvenates its insulating properties between the electrodes.
Following this, the next pulse voltage sparks a discharge at another nearby point between the electrodes, continuously generating spark discharges. Each pulse discharge erodes a tiny amount of metal. However, with the high frequency of thousands of pulses per second, substantial cumulative metal removal is achieved, thereby ensuring a high level of productivity.
By maintaining a consistent discharge gap between the tool electrode and the workpiece, the erosion of the workpiece metal proceeds as the tool electrode advances towards it. Consequently, the machined shape mirrors that of the tool electrode. By altering the tool electrode's shape and its relative motion to the workpiece, complex profiles are crafted with precision. Materials with excellent electrical conductivity, high melting points, and ease of processing, such as copper, graphite, copper-tungsten alloy, and molybdenum, are typically employed for tool electrodes. Despite the tool electrode experiencing minimal wear compared to the workpiece's corrosion, the loss is often negligible.
Serving as the crucial discharge medium, the working liquid is indispensable for cooling and chip removal during the machining process. Preferred working liquids include those with low viscosity, high flash points, and stable performance, such as kerosene, deionized water, and emulsion. EDM machines function based on self-excited discharge principles: the spark discharge between the electrodes initiates with a high voltage, breaking down the medium as the electrodes approach each other, igniting a spark. The discharge causes a significant drop in resistance and voltage. The spark channel must extinguish rapidly (within 10-7 to 10-3 seconds) to maintain the 'cold pole' characteristic, ensuring that the channel energy impacts only a small area, thus causing localized erosion of the electrode. This material removal technique is known as EDM.
