Abstract : This paper reviews the technical advantages, key technologies, implementation conditions, and applications of high-speed machining. Keywords: high-speed machining , machining center manufacturing technology. Since the 1990s, high-speed machining (HSC) has become one of the important development directions of modern CNC machining technology. The great attraction of high-speed machining lies in ensuring high-precision machining while achieving high-speed machining. The recognition and strong demand for high-speed machining in the aerospace, automotive, and mold manufacturing industries have promoted the rapid development of high-speed machining technology internationally. For example, at the 1997 Beijing International Machine Tool Exhibition, machining centers with spindle speeds between 10,000 and 20,000 r/min already had a considerable presence. 1 Technical Advantages of High-Speed ​​Machining The aerospace industry and mold manufacturing industry are two important application areas of high-speed machining. Although aerospace manufacturing companies began high-speed machining of aluminum parts about 20 years ago, it has not received the attention it deserves. With the development of technology, product diversification and small-batch production have led to a significant increase in machining operations. Achieving high precision while ensuring high-efficiency machining has become the development trend of high-speed machining. Major machine tool manufacturing countries worldwide, such as the United States, Germany, and Japan, have conducted extensive research in this area and are continuously launching high-tech, high-speed, and high-precision machine tools. High-speed machining represents a breakthrough in the understanding of traditional cutting principles. According to reports, high-speed machining experiments abroad have confirmed that when the cutting speed exceeds a certain value (V=600m/min), further increases in cutting speed actually decrease the cutting temperature. The heat generated during the cutting process enters the chips and is carried away from the workpiece. Tests under laboratory conditions have shown that in most applications, the workpiece temperature rise during cutting does not exceed 3℃. Correspondingly, under a given metal removal rate, when the cutting speed exceeds a certain value (approximately 300-500m/min), the actual cutting force decreases with increasing cutting speed. After the cutting speed continues to increase to a certain value, the actual cutting force remains approximately constant.
