"高速走丝电火花线切割精加工编程设计：提高模具表面质量和使用寿命"。

With the rapid development of molds in recent years, the requirements for surface quality of mold processing have been continuously increasing, and the surface finishing technology of wire electrical discharge machining (WEDM) has attracted much attention. This requires WEDM to improve the mechanical properties of the processed surface and reduce surface roughness, thereby increasing the service life of the mold. This paper introduces the machining principle and application of working medium in WEDM. The basic principles and laws of traditional WEDM are explored and introduced. The development of new methods in WEDM is described, which can improve machining accuracy under suitable conditions. In high-speed wire EDM, the machining reaction force is small and the wire electrode vibration is also minimal. In addition, because the discharge gap can be narrower than traditional WEDM under certain conditions, the workpiece erosion can also be minimized. High-precision finishing can be achieved in high-speed wire EDM. This paper introduces the phenomena that occur in the WEDM process and provides explanations, along with programming design examples using Mastercam X2 software. Keywords: wire electrical discharge machining; finishing; Mastercam X2 software.
