High-speed cutting processing technology has been widely used in the automobile mold manufacturing industry at home and abroad, and has achieved huge benefits, but the mechanism and related theories of high-speed cutting processing are still incomplete, and the high-speed cutting database for automobile molds has not been established. Domestic and foreign companies still use the traditional "trial cutting method" and "empirical method" to select high-speed cutting tool parameters and high-speed cutting processing parameters. When processing a new material, it is often necessary to use multiple tools for repeated cutting tests. , Research and analyze tool wear, damage methods and their causes, and find a set of best tool materials and processing parameters. Repeated so many times, blindness is large, and a lot of manpower, financial resources and resources are wasted. For the high-speed cutting of special materials such as alloy cast iron, high-strength alloy steel, super alloys (such as titanium alloy) and other materials, how to choose suitable cutting tools according to material characteristics and how to design reasonable cutting parameters is still being researched and developed. middle.

High-speed machining technology is an advanced manufacturing technology in the 21st century, with strong vitality and broad application prospects. High-speed cutting technology can solve a series of problems that are plagued by conventional cutting of automobile molds. In recent years, high-speed cutting technology has been widely used in most of the mold companies in developed countries such as the United States, Germany, and Japan. About 85% of the mold EDM processing procedures have been replaced by high-speed machining. High-speed machining technology combines high efficiency, high quality and low consumption, and has become the mainstream of the international mold manufacturing process.
