Analysis on the application of CNC machining technology in automotive machinery mold processing and manufacturing

1 Related connotations of CNC machining technology

With the development of information technology, CNC machining service technology emerged at the historic moment. As a new type of manufacturing technology, CNC machining technology mainly uses computer technology to control mechanical processing and manufacturing. Therefore, compared with traditional mechanical processing, you will find that CNC processing technology has the characteristics of informatization and automation [1].

CNC machining technology relies on computers and programming to code all parts for machining, including the size, material, performance, etc. of the parts, and then uses the collected information to complete automated manufacturing of the parts. The most important equipment in CNC machining technology is CNC machine tools. Compared with traditional machine tools, CNC machine tools greatly reduce labor costs during use, mainly because in CNC machine tools, workers only need to input various data of the mechanical mold into the CNC machine tool to achieve automated production. In CNC machining technology, CNC machining machines and computer programming are both important components. They help and cooperate with each other to achieve the efficiency and scientificization of CNC machining technology.

CNC machining is mainly divided into two parts: hardware and software to realize processing. Software is computer technology and program coding, and hardware is CNC machine tools and other mechanical equipment. CNC machine tools are the core part of the entire CNC machining technology. During the work process, you only need to input program data to perform automated production work. Various parts processed by CNC are highly accurate and can save most of the manpower and material resources.

CNC machining technology emerges based on the continuous development of science and technology, and its main application feature is a high degree of automation. During the use of CNC machine tools, simple and concentrated operations can save a lot of time, reduce space requirements, and achieve flexibility in processing.

2 Advantages of CNC machining technology

2.1 Reduce labor costs

When using CNC processing technology, most of them appear in the form of digital production lines. The digital production line replaces the traditional manual assembly line, which greatly reduces labor costs. Assuming that it takes 50 people to produce a batch of parts on a traditional production line, then after using a digital production line, the same parts only require 7 to 8 people to complete the supervision of the production process. In this way, you can intuitively feel the application by comparison. CNC machining technology is important in reducing enterprise production costs. Even when using digital production lines, CNC machine tools need to be inspected and maintained regularly, but compared with the cost of labor, it is still a very small part. Therefore, using CNC machining Technology has high economic value to enterprises. Since CNC machining technology has the characteristics of automation, even if an accident occurs during the production process, the digital assembly line will immediately send out an alarm signal and stop production. This ensures the safety of workers to a certain extent. From this point we can also see the superiority of CNC machining technology.

2.2 Improved the professional skills of staff

According to the current situation of social productivity, it can be clearly seen that most of the personnel working on the assembly line do not have a high level of education, which is detrimental to the development of the enterprise. In the process of production management, because the staff’s level of education is not high, it leads to Staff members often operate illegally, which makes production management difficult and causes unnecessary economic losses to the company. Since CNC machining technology requires users to have certain professional qualities and be able to operate CNC machine tools and computer programs,Therefore, the cultural literacy of staff should also be continuously improved to adapt to the needs of society. When operating CNC technology, staff are required to have certain knowledge of mechanical manufacturing principles and computer programming skills. Therefore, when using this technology, staff are also required to improve their professional qualities and professional skills to promote their own development.

2.3 Realized the automation of automotive machinery mold processing and manufacturing

CNC machining technology directly uses computer technology to control production equipment. In this process, it promotes the automated production of equipment by improving the convenience of equipment operation. In the process of using CNC machining technology, although workers need to set various parameters of the production parts in advance in the computer program, CNC machining technology itself is an automated manufacturing technology [2]. The automation of automotive machinery molds is an important breakthrough in the automotive manufacturing industry. It can not only promote the development of automotive manufacturing methods in a more modern direction, but also reduce the quality of parts that are unqualified due to human factors in the production process of automotive machinery molds. situation, which greatly reduces the production cost of the enterprise. With the continuous development of science and technology, efforts to improve the automation of automotive machinery mold manufacturing and processing can not only provide direction for the manufacturing form of automotive molds and promote the development of the automotive manufacturing industry, but also promote the production efficiency of automotive machinery molds, laying the foundation for an early date. It lays the foundation for the automation and intelligence of automotive machinery molds.

In the process of producing automotive machinery molds, they are often affected by some external factors, resulting in substandard quality of automotive machinery molds. In the traditional production process of automobile machinery molds, due to the inability to control the quality of mechanical molds well, a large number of defective products often appear during the production process, causing serious economic losses to the enterprise and affecting the enterprise. economic benefits. However, with the emergence of CNC machining technology, in the process of producing automobile mechanical molds, it can not only improve the accuracy of mechanical molds, but also improve the performance of mechanical molds, reduce the occurrence of defective products, and reduce the cost of automobile companies in the production process. reduce costs and promote the development of automotive machinery molds.

3.2 Application in automotive machinery mold manufacturing

In the process of manufacturing automotive machinery molds, a large amount of accurate data is required to complete the manufacturing work. In this process, through computer technology, a large amount of accurate data can be obtained to deal with detailed issues. Therefore, automobile companies should strengthen the cooperation between CNC processing technology and computer technology, and use the two technologies to improve the production quality and manufacturing level of automobile machinery molds.

Mold manufacturing has a certain degree of complexity.
