WEDM machine tool is an original EDM machine tool in China, which is widely used in the fields of mold manufacturing and parts processing, and occupies a considerable weight in the low-end market. At present, how to develop WEDM machine tools is a topic of great concern to the electric machining industry. We must learn from the successful experience of foreign countries, foster strengths and avoid weaknesses, directly apply the latest achievements of today's computer technology, and develop a powerful CNC system based on PC as soon as possible, laying a good foundation for the hardware development of WEDM. At the same time, pay attention to the combination of artificial intelligence technology and high-speed wire cutting machine, and use computer software technology to improve the performance of machine tools. In addition, strengthening the research of machine tool bed and applying various cutting technologies will greatly improve the overall processing level of machine tools and continuously enhance the competitiveness of high-speed WEDM in the market. While applying new technologies and new processes, we must also pay attention to the in-depth and detailed basic theoretical and experimental research on WEDM process rules, which is also a very important link.
