[0002] Precision forging refers to the forming technology that only needs a small amount of processing or no processing after the parts are forged to meet the requirements of the parts. Precision forging is an important part of advanced manufacturing technology and is also a widely used parts manufacturing process in the automotive, mining, energy, construction, aviation, aerospace, weapons and other industries. Precision forging not only saves materials and energy, reduces processing procedures and equipment, but also significantly improves productivity and product quality, reduces production costs, and thus improves the market competitiveness of products. At present, there are many precision forging processes that have been applied to production. According to the different forming temperatures, they can be divided into hot precision forging, cold precision forging, warm precision forging, compound precision forging, isothermal precision forging, etc. Forging, etc. With the development of the manufacturing industry, the requirements for precision forging parts are getting higher and higher, and higher requirements are also put forward for the research and development of precision forging technology. Continuous process innovation, in order to meet the requirements of formed parts and reduce production costs, it is necessary to continuously develop new precision forging processes with high forming accuracy, long mold life and high production efficiency. The development of composite processes, with the continuous improvement of the process requirements for formed parts, it is difficult for a single precision forging to meet the requirements. This requires the development of composite forming processes, combining forging processes with different temperatures or different process methods, and completing the processing and manufacturing of a part by taking advantage of each other's strengths and weaknesses. Precision forging processes can also be combined with other precision forming processes such as precision casting, precision welding and other processes to improve the application range and processing capabilities of precision forming processes. Knowledge-based process design, with the continuous development of precision forging technology, process design is becoming more and more complex. In order to improve the reliability and efficiency of process design, the development of knowledge-based expert systems is an important research direction for future precision forging process design.
