CNC machining often reminds people of complex designs and small products or parts. For those who are not familiar with this technology, it stands for “computer numerical control” and refers to a machine that can shape materials according to digital instructions.
These machines can work more accurately than human manufacturers, and can proceed fairly quickly with little waste. Similarly, the process is usually associated with smaller products, perhaps as part of a larger mechanism.
With the rapid development of the automobile industry, the efficient, high-precision, and high-stability processing of complex key parts of automobiles has become an effective measure to shorten the production cycle of products and improve the efficiency and competitiveness of enterprises. CNC machining technology can realize rapid prototyping and manufacturing of complex auto parts. At the same time, virtual manufacturing technology, flexible manufacturing technology, and integrated manufacturing technology in CNC technology have been widely used in modern automobile processing and manufacturing. The intelligent development of CNC manufacturing technology in the production process of auto parts will become a development trend of the auto manufacturing industry.
With the introduction of Industry 4.0 and the Made in China 2025 core plan, it signals the arrival of the fourth industrial revolution in the world. More emphasis is placed on the integration of informatization and industrialization of the product manufacturing process to realize the intelligentization of manufacturing equipment and its control, such as intelligence factory, intelligent production, human-computer interaction, Internet of Things, machine self-organization, digital manufacturing, etc. CNC machine and CNC systems are the core elements to realize intelligent production. CNC machining technology can realize rapid prototyping manufacturing of complex auto parts, and virtual manufacturing technology, flexible manufacturing technology, and integrated manufacturing technology in CNC technology are gradually being processed in modern automobiles. It has been widely used in manufacturing. The intelligent development of CNC systems in the manufacturing process of auto parts will also become an inevitable development trend in the modern auto manufacturing industry.
The Importance Of CNC Machining In The Manufacturing Of Auto Parts
Today’s CNC operations can involve 3-axis and 5-axis machining and turning with powered tools. These functions more or less provide more ways of manipulating and manipulating materials for the machine, so that they can not only trim curves, but also trim curves instead of right angles, and generally produce more complex results. Naturally, this has led to a wider range of applications, including some important auto parts.
Compared with manual manufacturing, CNC machining technology has laid the foundation for realizing the standardization and standardization of auto parts manufacturing, and improving the production quality and actual equipment rate of domestic auto parts. CNC technology can provide a complete set of automation solutions for the manufacturing of key automotive parts. It receives processing data based on the industrial Internet and big data monitoring and remote services in the machining process, and then performs virtual processing and program code inspection, and then uses the processing status of the CNC system to automatically perception, self-learning, self-adaptation, and self-optimization functions to achieve high-quality machining of workpieces, and then use industrial robots and CNC machine tools online batch inspection methods to realize the wide application of CNC machine tools in the efficient flexible machining and batch manufacturing of key automotive parts .
The Status Quo Of CNC Custom Machining In The Automotive Industry
Some companies, such as Porsche, have turned to CNC machining customization, producing equipment for rare and limited-run vehicles, or any vehicles that may not be accessible to owners or stores.
Traditionally, if the warehouse ran out of any of the 52,000 different parts that make up the Porsche classic catalog, specific tools were needed to make more parts. CNC machining customization is not the case. This process is more cost-effective than reworking the factory to manufacture specific parts, and it can reduce the amount of warehouse space required because each part can be ordered within a few hours or days.
Porsche tested this move through CNC machining and customizing the full-function clutch release lever of the Porsche 959. The lever must pass the same tests as the original machined parts, including a 3-ton pressure test. The manufacturer plans to add 20 parts to its digital library as part of the pilot program, and then expand as needed.
Custom car design is limited to ordinary car owners. The driver can choose the interior and exterior colors and accessories, but the brand, model and appearance of the vehicle are the same as other specific models on the road. For buyers with a large amount of funds, Rolls-Royce is committed to using CNC machining customization to create fully customized vehicles.
The skill of this type of CNC machining customization does not lie in technology. In fact, 30% to 40% of new Rolls-Royce drivers choose an inventory model from a dealer instead of ordering a customized model for themselves. Provide them with the option of creating custom vehicles, they can design everything from the frame and body to the interior entertainment console, which may increase the luxury car industry in ways that manufacturers did not expect.
Prospects For The Development Trend Of Future CNC Systems
Facing the demand for high-quality and high-efficiency integrated intelligent production and manufacturing of complex parts with multiple degrees of freedom, the future CNC system will develop in the direction of multi-degree-of-freedom compound processing, realizing the completion of turning, milling and drilling of multiple processing surfaces in one installation. Multi-process compound processing. In addition, the CNC system needs to have more advanced trajectory planning strategies and motor control strategies to achieve high-speed and high-precision machining. With the development trend of intelligent manufacturing, the CNC system needs to have a highly intelligent human-machine interface, and realize the machining technology planning function and the diagnosis and adaptive control strategy of the machining process. The future CNC system will realize all-round self-monitoring and management throughout the entire process of machine tool manufacturing. The CNC system can automatically plan the installation position, machining trajectory and machining tools according to the 3D model of the parts. It is more likely to use Ethernet and Internet technology to realize the communication and cooperation of the machine in the factory, and the planning time is the shortest process step. The communication of the manipulator realizes automatic loading and unloading, loading and handling, etc., and realizes the automatic and intelligent rapid prototyping manufacturing of key complex parts.
