The advantages and development trends of CNC Machining indicate that its importance in the manufacturing industry will continue to increase. In continuo progresso tecnologiae et expansione scenariorum applicationis CNC machining amplius applicabitur et in pluribus regionibus developintur. 1, sunt multa avantiae machinae CNC, inter quas maximus qualitatem eius, altam efficientiam et altam precision. The specific advantages are as follows: improves machining accuracy and ensures machining quality: CNC machining uses digital information to define the machining process of parts, which can accurately control the size, shape, and positional accuracy of the workpiece, i avoiding human errors and machine tool errors in traditional machining methods. Improving production efficiency: CNC machining can achieve automated processing, greatly improving production efficiency, shortening production cycles, and reducing production costs. Strong flexibility: CNC machining can easily adjust machining parameters and process flow to meet the machining needs of different specifications and shapes of parts. Improving working conditions: CNC machining can achieve functions such as automatic tool changing and automatic clamping, i reducing the labor intensity of workers and improving work efficiency. Beneficial for achieving modernization of production management: CNC machining can be combined with modern production management technologies such as computer-aided design (CAD) and computer-aided manufacturing (CAM) to achieve digital, networked, and intelligent production management. 2,In terms of development trends, CNC machining will move towards the following directions: high-speed development of industries such as automobiles, national defense, aviation and aerospace, as well as the application of new materials such as aluminum alloys, i the demand for high-speed CNC machine machining becomes increasingly high. In futuro instrumenta CNC machinae superiora velocitas spindle, celeriora fluctus et breviariora tempora cuta habebunt. Precisio alta: cum increasinge require partis accuractis in industria fabricationis, precision machinarum CNC continuabit melior. In futuro instrumenta CNC machinae superior positiones accuracionem habebunt, repetabunt positiones accuracionem, et contour accuracionem. Composite processing: Composite processing can complete all complex parts on one machine tool, avoiding workpiece handling and multiple clamping between processes, shortening the processing chain, and improving processing quality. In the future, i CNC machine tools will have more composite machining functions, such as turning milling composite, milling grinding composite, etc. Intellectus: Intellectus est unus de principibus tendentibus ad elaborationem instrumentorum CNC machinarum. In futuro instrumenta CNC machinae habebunt magis functiones intellegentes, sicut controlum adaptive, programmationem automaticam, monitorem intelligentem etc. Greening: With the increasing awareness of environmental protection, green manufacturing has become one of the important development directions of the manufacturing industry. In the future, CNC machine tools will pay more attention to the application of green manufacturing technology, i such as the recycling of cutting fluids and waste disposal. Networking: Networking is one of the important trends in the development of CNC machines tools. In future, CNC machine tools will be combined with technologies such as the Internet of Things and cloud computing to achieve remote monitoring, fault diagnosis, and other functions, improving equipment utilization and management efficiency.
