At present, domestic and foreign scholars use high-speed photography, scanning electron microscope and other modern measuring instruments and experimental methods to study the basic theory of EDM based on theoretical and practical monitoring methods, mainly focusing on EDM simulation technology and micro-electricity. Spark processing scale effect, EDM discharge channel, EDM surface quality, multi-channel multi-electrode EDM technology, EDM machining technology, EDM process control, etc., effectively validate the EDM technology The polar effect, covering effect, gap effect, area effect, pulse discharge characteristics, medium effect, electrode and workpiece material characteristics not only lay a solid foundation for the improvement of EDM technology level, but also give more focus on future development. Guidelines. The demand for multi-axis linkage EDM processing technology and equipment is becoming more and more urgent, such as the processing of key components of complex surface structures in the aerospace, aerospace and energy fields, the processing demand of nickel-based high-temperature heat-resistant alloys and titanium alloy materials, and the rapid development of China's precision mold manufacturing industry. With the support of the national 04 special "five-axis linkage precision CNC EDM machine tool for complex surface processing of special materials" and "ultra-precision micro-EDM equipment and technology (six-axis linkage) for aerospace complex parts" The improvement of the company's own technology has made great progress in China's four-axis, five-axis, six-axis linkage precision CNC EDM processing technology and equipment. China has a series of independent and intellectual property rights, a five-axis, six-axis linkage precision CNC EDM machine tool, which realizes complex surface structure parts with difficult-to-machine materials such as integral turbine disk and closed integral impeller. The processing of high-precision mold products fills the gaps in domestic products and technologies. Due to the precision and profiling of EDM technology, it has certain limitations in processing efficiency, and in actual production, there is a strong demand for EDM composite high-efficiency machining technology and high-efficiency micro EDM technology. Micro EDM pulse power supply and CNC system new technology, micro EDM assisted machining technology, EDM high speed arc discharge machining technology based on cluster electrode, arc ignition processing technology, high efficiency CNC discharge milling, ultrasonic assisted EDM milling The application research of a series of technologies such as technology, arc mechanical composite cutting technology and short arc machining has achieved certain application effects in improving the efficiency and micro-effect of EDM technology, and has strong product development and market prospects in the future. With the serialization, productization degree and market share of domestic superhard tool products, the numerical control and automation level of super-hard tool EDM special machine tools are increasingly urgent, and the research and development of this direction product has been greatly improved. With advancement space; the product category of EDM technology has been developing steadily, but with the diversification of EDM technology, product diversification and the demand for green manufacturing, its research is also a key point in the future. With the introduction of "Made in China 2025", EDM has gradually broken the intelligence of single-machine equipment, intelligent design of process design, intelligent processing process, and the development of digital, network and intelligentization of EDM. Really achieve "difficult to attack, precise and efficient, interconnected, and reliable." We are also looking forward to working with colleagues in the industry to discuss reliable, composite, green, efficient, and sophisticated EDM equipment by sharing the needs of EDM processes in key applications such as aerospace, aerospace, automotive, energy, and precision molds. New methods, new technologies and attention to equipment interconnection technologies and standards will jointly promote EDM to digital, intelligent and service-oriented technology, and add luster to the magic spark business.
