Since the world's first CNC system using vacuum tubes was installed in a 3-axis continuous control milling machine (developed in collaboration between Parsons and MIT) in 1952, breakthroughs have been made in microelectronics, automatic control, computer technology, and precision machinery. The development of CNC machine tools, integrating these technologies, has been rapid and ever-evolving. A CNC machine tool is a machine tool equipped with a program control system. It is also a typical mechatronics product. With the advancement of modern manufacturing technology and the continuous improvement of people's living standards, the market demand for personalized products is increasing daily. Therefore, the production of small and medium-batch parts is increasing, and the requirements for part precision are becoming higher, with increasingly complex shapes. Thus, the rapid development and widespread application of CNC machine tools, as the most important processing equipment for achieving flexibility and automation, has become a reality. Flexible manufacturing cells (FMC), flexible manufacturing systems (FMS), and computer integrated manufacturing systems (CIMS) all use CNC machine tools as basic equipment. Therefore, modern CNC machine tools are required to develop in the following ten aspects. 1. High Speed Modern CNC systems have transitioned from 16-bit CPUs to 32-bit CPUs, and some new CNC systems abroad have adopted 64-bit CPUs, using RISC chips with reduced instruction set computing as the main CPU to improve processing speed. The setting unit and rapid feed rate of modern CNC machine tools have reached 0.01μm~tm and 10~24m/min, or even higher. 2. High Precision The role of the servo system is to accurately track and position the machine according to the given motion speed and trajectory using commands. The quality of the servo system directly affects the machining accuracy of the CNC machine tool. Modern CNC machine tools use AC digital servo systems and employ new control theories to achieve high-speed response servo systems. Some new CNC systems have sensors and software with thermal compensation and spatial error compensation functions (such as compensating for backlash errors in lead screws and gears). This perfectly resolves the contradiction between high speed and high precision. 3. High Automation During the machining process, CNC machine tools can operate completely automatically according to a pre-programmed sequence, including tool feed and workpiece inspection. Operators require no intervention; they only need to issue start commands and monitor the process. Modern CNC machine tools are equipped with advanced monitoring and detection devices. Once faults such as workpiece deviations or tool wear are detected, timely alarms are triggered, and compensation or tool replacement is provided, greatly improving the automation level of CNC machine tools and enabling continuous, long-term automated machining while ensuring product quality. 4. High Efficiency Modern CNC machine tools generally employ automatic tool changers and automatic workpiece changers, achieving multi-functionality. By concentrating processes, they reduce the number of clamping operations, turnaround time, number of fixtures, number of operators, and floor space, thereby shortening auxiliary time. Both roughing and finishing can be performed on the same CNC machine tool, improving its utilization rate. Modern CNC machine tools also use high-power motors and are equipped with corresponding new cutting tools, improving cutting efficiency, shortening machining time, and resulting in significant economic benefits. 5. High Flexibility A crucial aspect of CNC machining is the programming of CNC machine tool parts. Modern CNC machine tools utilize the high storage and computing power of CNC and employ automatic programming technology. This allows for online programming of parts on the CNC system. It features human-machine interface functionality, enabling program input, editing, modification, and deletion, with both foreground and background editing capabilities, as well as macro program design functions. In this new CNC system equipped with a small machining database, the optimal tool and cutting parameters are automatically selected based on machining requirements, exhibiting adaptive control capabilities and even displaying results in 3D color dynamic graphics. This significantly shortens the product development cycle, providing a shortcut for new product development, product improvement, and modification. 6. High Reliability The new CNC machine tools utilize large-scale or very large-scale integrated circuits. Employing dedicated chips and hybrid integrated circuits, it achieves 3D high-density mounting technology, improving circuit integration. This reduces the number of electronic components, simplifies the CNC machine tool's structure, thereby avoiding workpiece scrap and improving the reliability and safety of the CNC machine tool. It also possesses strong fault self-diagnosis and protection functions. To adapt to the different requirements of various machine tools, modern CNC machine tools using CNC systems only require changes to the software or control program; in terms of CNC system hardware... Different functional modules can be selected to form a CNC system that meets user needs, ensuring product quality. 7. Excellent Operation Functions The new CNC machine tool has a user-friendly human-machine interface. It uses a color CRT or LCD screen for display or prompts, combined with a manual operation keyboard, and utilizes menu selection for operation modes, greatly facilitating the operator. The number of buttons and indicator lights on the operation panel has been reduced, and operation method prompts are provided, reducing operational errors. 8. Powerful PLC Functions Modern CNC machine tools are equipped with a programmable logic controller (PLC), organically combining CNC and PLC. The ladder diagram (LAD) monitoring function facilitates machine tool fault diagnosis and maintenance. Powerful PLCs also have the capability of multi-axis linkage (simultaneous control). 9. Good Environmental Performance The new CNC system has high comprehensive and optimized resource utilization. Modern CNC machine tools generate less noise and waste during operation, having a smaller impact on the ecological environment, which is beneficial to workers' occupational health, reduces the labor intensity of operators, and improves safety. This results in a good working condition for operators, meeting the development needs of modern society. 10. Advanced Networking and Communication Capabilities To meet the requirements of FMC, FMS, and CIMs, CNC systems generally come equipped with RS322 and RS422 standard serial communication interfaces, enabling data exchange with a host computer. In high-end CNC systems with DNC interfaces, direct control and data communication between the CNC machine tool and the computer can be achieved, thus realizing drawing-free automation from design to manufacturing. To adapt to multi-level machining automation requirements and meet the networking needs of different manufacturers for different types of CNC machine tools, a MAP communication interface module has been developed. In recent years, MAP version 3.0 has been adopted, allowing data communication between devices from different manufacturers and enabling this data to be applied to all aspects of the factory. The implementation of MAP industrial control enhances product market competitiveness and creates favorable conditions for modern CNC machine tools to enter FMS and CIMs.
