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.
