This requires improving mechanical properties of WEDM machining surface, and reducing the surface roughness, so as to achieve the purpose of improving the mold life. This article describes the application of the WEDM processing principle and media. Explores and introduces traditional EDM wire cutting basic principles and laws. Describes the development of the WEDM new method, it can improve the precision under the proper environment. Since the processing reaction force is small in the Wire Electrical Discharge Finishing, wire electrode vibration. In addition, the discharge gap under certain conditions is narrower than traditional EDM wire cutting, so the specimen corrosion can also be smaller. High-precision finishing can be achieved in the occurred in the processing and interpretation of wire cut instance of programming design combined with Mastercam X2 software.
