[0002] Machining is a way of processing parts, which is to process raw materials to make them into the final requirements with relatively high precision and quality. Machining involves many technologies and processes, and can be processed by almost all raw materials, such as metal, plastic, powder metallurgy, etc. The emergence of machining can not only produce high-precision parts, but also improve production efficiency.

[0003] The machining process includes design, CAD analysis, transmission, programming, process analysis, equipment reorganization, processing, inspection and maintenance. Among them, the design and process analysis are very important. The accuracy of these two links determines the quality of machined parts. Designers need to make accurate drawings of parts, including specific dimensions and requirements. Process analysis requires analyzing the processing plan and making a reasonable process plan. The key part of machining is the machine tool, which is a machine used to process raw materials. Machine tools are used for cutting, drilling, milling, turning, high-speed milling, CNC machining and other aspects. The accuracy and quality of machine tools are the key to machining. The manufacture of machine tools requires strict control of all aspects of materials, design and manufacturing to ensure the quality of machine tools.
