1. Development of high-precision and ultra-precision machining
With the continuous improvement of CNC technology, the machining accuracy of modern CNC machine tools has reached the nanometer level, especially in high-end fields such as aerospace, automobile manufacturing and electronics industry, ultra-precision machining has become a trend. For example, the application of high-speed five-axis CNC machine tools can reduce the number of clamping times, improve the machining accuracy of complex molds, and reduce human errors. In addition, the application of linear motor drive, intelligent compensation technology and high-precision tools makes the tolerance control of mold manufacturing more stringent and meets the needs of ultra-precision machining.
2. Trends in intelligence and automation
The combination of artificial intelligence and Internet of Things (IoT) technology has made CNC equipment develop in the direction of intelligence. Modern CNC systems are equipped with intelligent monitoring functions, which can analyze the machining status in real time, optimize machining parameters through adaptive control, and reduce scrap rate. In addition, CNC technology is linked with industrial robots to achieve automatic tool change, automatic detection and remote control, and improve the flexible production capacity of mold manufacturing. Intelligent CNC systems can also combine big data analysis to perform predictive maintenance on equipment, reduce equipment failure rate and improve production efficiency.
3. Efficient and high-speed processing technology
Efficient processing is one of the core goals of CNC technology development. Modern CNC machine tools use high-speed spindle technology, optimized tool path algorithms and dynamic balancing systems to greatly improve cutting speed and feed rate. For example, the application of HSC (high-speed cutting) technology can reduce thermal deformation, improve surface quality and reduce processing time. Compared with traditional slow processing, high-speed processing can significantly improve the production efficiency of molds and shorten product delivery cycles.
4. Green manufacturing and energy-saving and environmental protection technology
Against the background of global advocacy of sustainable development, CNC technology is also developing in the direction of green and environmental protection in mold manufacturing. For example, the application of dry cutting, low-emission coolant and energy-saving servo system can reduce waste liquid and energy consumption in the processing process. In addition, the combination of additive manufacturing (3D printing) and CNC technology is also gradually applied in mold manufacturing to reduce material waste, improve resource utilization, and achieve a more environmentally friendly production method.
5. Composite processing and multi-material compatibility
In order to meet the needs of modern manufacturing for complex molds, CNC technology is developing towards multifunctional composite processing. For example, the combination of turning and milling, laser-assisted cutting, ultrasonic-assisted processing and other technologies can efficiently process high-hardness materials such as titanium alloys and carbon fiber composites to meet the requirements of high-end mold manufacturing. In addition, the combination of CNC technology and additive manufacturing (such as metal 3D printing) also provides more possibilities for mold design and manufacturing.
