With the rapid development of electronic technology and automation technology, the application of numerical control technology is increasingly widespread. Numerical control equipment based on microprocessors and marked by large-scale and very large-scale integrated circuits has been widely used in the field of equipment manufacturing in my country. This aspect has created necessary conditions for the development of my country's machinery manufacturing industry; on the other hand, the technological advancement, structural complexity and high intelligence of these CNC equipment have also caused equipment failure maintenance to occur in theory, technology and means. Great progress.
Obviously, any numerical control equipment is a kind of process control equipment, which requires it to work accurately under control at any time during the working process. The CNC machine tool is a complex working system, any part of which fails, it will cause the machine tool to stop, leading to production halt.
Many enterprises in my country's equipment manufacturing industry often need to spend huge amounts of money to introduce CNC machine tools, and these equipment are also placed in key positions in the production process of the enterprise. After a failure occurs, once it cannot be repaired and eliminated in the first time, it will cause serious economic losses. In addition, my country's equipment manufacturing level and personnel quality are relatively low, and it is more important to strengthen the fault diagnosis of CNC machine tools.
