The importance of CNC system in the manufacturing process of auto parts
With the rapid development of the automotive industry, high-efficiency, high-precision, and high-stability processing of complex key components of automobiles has become an effective measure to shorten the production cycle and improve the efficiency and competitiveness of enterprises. CNC machining technology can facilitate the rapid prototyping of complex automotive parts. At the same time, virtual manufacturing technology, flexible manufacturing technology, and integrated manufacturing technology in CNC technology have been widely used in modern automotive processing and manufacturing. In terms of manual manufacturing, CNC technology lays the foundation for the standardization and standardization of auto parts manufacturing, and the improvement of the production quality and actual equipment rate of domestic auto parts. CNC technology can provide complete automation solutions for the manufacture of key auto parts. Based on monitoring and remote service of industrial Internet and processing process, remote processing receives data, and then carries out virtual machining and program code detection. Next, it uses the processing status of the CNC system. Perceiving, self-learning, self-adaptive and self-optimizing functions realize high-quality machining of workpieces. Then, online robots and numerically-controlled machine tools are used for online bulk detection methods to realize the wide application of CNC machine tools in high-efficiency flexible machining and mass production of key automotive components. .
Commonly used numerical control system types in the manufacture of automotive parts
At present, domestic CNC machine tools and Japanese, American, and European imported machine tools are mostly FANUC and SIEMENS. Both can use G code to achieve programming. Among them, most of the turning and multi-axis milling CNC machine tools use the above two kinds of CNC systems, and are easy to integrate with computer-aided design. The above two CNC systems occupy most of the market share of today's CNC machine tools. Nowadays, some German multi-axis machining centers for complex surface machining are equipped with HEIDENHAIN CNC system. This system has the ability to visualize and modular large-scale program editing. It can quickly insert and edit information and realize complex surfaces. Porous structure for rapid prototyping. With the continuous development and establishment of intelligent manufacturing and smart factories, some machine tool companies have started to develop special CNC systems according to customer requirements, such as OKUMA, YAMAZAKI MAZAK, and DMG. (DMG MORI) company, China Shenyang Machine Tool (SMTCL) company.
The Characteristics of FANUC System in Intelligent Manufacturing and Its Improvement Measures
The FANUC system has powerful forces in the R&D, design, manufacture, and sales of today's world's CNC systems. Its product range covers a wide range of manufacturing processes such as turning, milling, grinding, machining centers and more. The FANUC numerical control system is more convenient, stable, and reliable to use, and its requirements for the industrial environment are relatively low. FANUC system uses a more general G code programming program, and the program statement structure is simple, the system is stable and reliable. The system can be directly programmed according to the part outline size specified on the parts drawing, such as straight line inclination, arc radius, chamfer value, etc., simple and intuitive. The FANUC system is able to self-plan roughing and finishing cycle paths and leave designer-specific machining allowances according to design values, simplifying complex programming. For porous parts, only the center position of the hole is required, and then a simple circulation instruction such as G82-G89 can be used to realize the porous automatic cycle processing. In the process of surface machining, macro programs (such as #1, #2, etc. are used as variables) can be directly programmed according to surface equations (equations containing variables #1, #2, etc.), which are intuitive, efficient, and practical. At the same time, the FANUC system has a convenient coordinate system transformation function, which can easily realize multi-coordinate system hybrid programming. The FANUC system has an intelligent human-computer interaction interface. All operations from the creation of the machining program to the actual machining can finally be debugged and simulated on the same screen, and easy programming, visualization, and inspection of the lathes, machining centers, and milling machine machining cycles. Features.
In terms of intelligence, the FANUC system can use a wealth of network functions to build a system suitable for CNC machine tools. It can also connect the CNC with a computer to perform 3D design of complex parts and NC code conversion (using CAM software) for subsequent NC program transmission. And monitor the CNC state to realize the intelligent manufacture of complex geometry parts. It is also possible to connect the machine tools in the factory via Ethernet to centralize, manage, control, and monitor the operating status of the machine tools and achieve a high degree of integration between the CNC and the computer. Figure 1 shows the application of FANUC System FS0i-F(C) in intelligent production or intelligent plant establishment. At present, the FANUC system has introduced real-time optimization control to realize the control of intelligent machine tools, and performs real-time optimization control according to changes in the mechanical conditions such as load, temperature and position. By using these functional groups, high-speed, high-precision, and high-quality machining are achieved. Especially in the processing of complex shapes such as automobile parts and metal molds, pre-reading program instructions are used to determine the shape of commands, speed and acceleration are properly controlled, smooth machining paths are obtained within tolerances, mechanical shocks are reduced, and CNC machine tools are used Excellent performance and intelligent manufacturing.
For the manufacture of thin-walled housing parts in the automotive industry, special milling processes such as engine housings and gearbox housings should be loaded with special post-processing procedures, such as machining chatter due to low-rigidity shells during machining. The reduction (Figure 2), loading adaptive speed control and machine torque, torque monitoring module, through the automatic adjustment of the spindle speed to achieve the torque stability of the various shafts to maintain stable state, improve processing quality and processing efficiency.
At present, OKUMA Corporation has installed this function in a self-developed CNC system, reducing the need for operators to have a lot of processing experience. At the same time, loading each axis motor torque and torque monitoring digital control module also helps to determine the momentary collision between the tool or the tool holder and the workpiece or the fixture in the cutting process, thereby urging the bed to move and protect the spindle from damage. In addition, it is hoped that the FANUC system will be loaded with on-line inspection modules such as Renishaw probes, especially for aperture detection and position detection of automotive porous parts, and integrate some simple three-dimensional detection functions into digital control systems for processing, inspection and repair. One-piece high-precision, high-efficiency machining mode.

And other multi-process composite processing. In addition, the numerical control system needs to have more advanced trajectory planning strategies and motor control strategies to achieve high-speed, high-precision machining. With the development trend of intelligent manufacturing, the CNC system needs to have a highly intelligent man-machine interface, and realizes the process planning function and the diagnostic and adaptive control strategy of the machining process. The future CNC system will realize the full production of the machine tool itself. Orientation of self-monitoring and management. The CNC system can automatically plan the mounting position, machining trajectory and machining tools according to the 3D model of the components, and it is more likely to use Ethernet and Internet technology to realize the mutual communication and cooperation among the various machine tools of the factory. The robot's communication realizes automatic loading and unloading, loading and handling, and realizes automatic intelligent rapid prototyping of key and complex components.
