1. Multifunctional
Modern CNC machines are equipped with an automatic tool changer, with a tool magazine capacity of up to 100 or more, allowing multiple machining centers to perform milling, boring, drilling, turning, reaming, tapping and other processes on the same machine simultaneously . Additionally, advanced CNC machines also utilize multi-spindle and multi-face cutting capabilities.
The CNC system allows data communication between CNC machines and can directly control multiple machines.
2. Higher speed, higher accuracy
Speed and accuracy are two critical factors in CNC machines, impacting machining efficiency and product quality.
The CNC system employs a high-frequency and high-precision processor to increase the system's basic computing speed. Furthermore, the use of ultra-large-scale integrated circuits and multiprocessor structures improves the system's data processing capability, specifically the speed and accuracy of interpolation operations.
The linear motor is used to drive the linear servo feed of the machine table, offering exceptional speed and dynamic response.
The implementation of feedforward control technology significantly reduces the tracking hysteresis error, thereby improving the accuracy of corner cutting during machining.
3. Intelligence
Modern CNC machine tools incorporate adaptive control technology, allowing the system to adjust work parameters in real time based on changing cutting conditions. This allows the machining process to maintain ideal conditions, resulting in greater precision, lower surface roughness and longer tool life, as well as greater production efficiency.
The CNC system has self-diagnosis and self-healing capabilities, which allow you to continuously monitor and verify the system and connected equipment. In the event of a failure, the system will trigger a failure alarm to indicate the location and cause of the problem and take appropriate action, such as shutting down. It can also automatically switch to a spare module to maintain unmanned operation.
To meet the growing demand for troubleshooting capabilities, the trend is toward the use of specialized artificial intelligence diagnostic systems.
4. CNC Programming Automation
With advances in computer applications technology, the use of interactive CAD/CAM automatic programming is becoming increasingly common in the field of CNC technology. This involves using a CAD drawing of the machining pattern and having the computer calculate and post-process the toolpath data to automatically generate the part's NC machining program, effectively integrating CAD and CAM.
CIMS technology now enables fully automated CAD/CAPP/CAM programming. Unlike the CAD/CAM system, the parameters of the programming process are obtained directly from the CAPP database within the system, without human intervention.
5. Greater reliability
The reliability of CNC machines is a major concern for users. To solve this, CNC systems use more integrated circuit chips and large-scale or ultra-large-scale integrated circuits to reduce the number of components and improve reliability.
By using hardware and software to adapt to various control functions and by using modular, standardized and generalized hardware structures, it becomes easier to improve production and quality control.
Automatic boot diagnostics, online diagnostics, and offline diagnostics help troubleshoot and alarm hardware, software, and external devices on the system. Alarm alerts enable immediate troubleshooting, and fault-tolerant technology and “redundant” design for critical parts enable self-healing. Various testing and monitoring technologies are also used to automatically protect against overproduction, knife damage, interference, power failure and other accidents.
6. Control system minimization
The miniaturization trend in digital control systems has facilitated the integration of mechanical and electrical components. The system now utilizes large-scale integrated components and multi-layer printed circuit boards, as well as three-dimensional installation methods to enable the installation of high-density electronic components while reducing the overall system size. The use of new thin color LCD displays instead of traditional cathode ray tubes has further miniaturized the CNC operating system. This makes it possible to mount the system directly on machine tool equipment, making it easier to use for operating CNC machines.
