Wire EDM processing is the processing of parts through the discharge principle of electric sparks. The workpiece is connected to the positive electrode of the pulse power supply, the molybdenum wire or copper wire is used as the cutting wire, the metal wire is connected to the negative electrode of the high-frequency pulse power supply as the tool electrode, and the processed parts are cut by spark discharge.

The pulse power supply provides the processing energy, and a special wire cutting working fluid is applied during the processing process to remove the debris generated during processing. Under the action of the electric field, the surface of the cathode and anode is bombarded by the electron flow and ion flow respectively, so that an instantaneous high temperature heat source is formed in the electrode gap to melt and vaporize the local metal.

The vaporized working fluid and the workpiece material vapor expand rapidly, and under the combined action of this thermal expansion and the stamping of the working fluid, the melted and vaporized workpiece material is thrown out of the discharge channel, and a spark discharge process is completed.
