Abstract
Electrical discharge machining (EDM) is widely used to machine difficult-to-machine materials with complicated shapes with high accuracy regardless of material hardness. However, the uneven distribution of the interelectrode gap width between the tool electrode and the workpiece hinders the limit of machining accuracy. In addition, the wear of the tool electrode degrades the machining accuracy, especially in sinking EDM, and the vibration and distortion of the wire electrode have a significant impact on the accuracy of wire EDM. Therefore, to overcome the machining accuracy of one micrometer in EDM, simulation technologies that can break the limit of precision in EDM are being developed.
