Electrode wear is not only the role of electrode properties, but also the role of power settings. The physical properties of the low-loss process are beyond the scope of this article, but can be simplified to a specific electrode-workpiece, two-stage, peak current, and a combination of timing currents that are re-plated back from the surface of the electrode during the duration of the spark Electrode surface. It should be noted that the material to be plated again is a combination of electrodes, workpieces and dielectrics, and there is a great difference in performance with the electrodes themselves. Low wear burning usually binds to the electrode positive while continuing for a while. Ideally, the electrodes will actually grow rather than wear. Needless to say, this is not a satisfactory result because the control of the electrode volume is not considered within the range.
