The machine tool is known as the "industrial mother machine", and the development of "high-end CNC machine tools" has always been an important part of the revitalization of my country's equipment manufacturing industry. In the process of moving from a big country of machine tools to a powerful country of machine tools, information technology has become an important tool for my country's machine tool industry to become bigger and stronger.

From the perspective of the development trend of numerical control technology, the integration of CAM (Computer Aided Manufacturing) and CNC (Numerical Control Machine Tool) can bring benefits to end users, which is a major trend. Of course, from a more long-term perspective, the three automatic systems of CNC system, motion control system, and automated drive system working under a unified drive platform are also the development trend of CNC technology.

The informatization of domestic machine tool companies mostly starts from unit products, such as CAD (computer-aided design), CAM, CAPP (computer-aided process design), etc. When the unit product applications of these tools become mature, how to improve the efficiency of collaborative work and integrate these unit products has become a common appeal of enterprise users.

The key to the future development of enterprise informatization lies in the integration of information and service capabilities, although people have a certain understanding of advanced technologies and products such as CAD, CAPP, CAE (computer-aided engineering) and digital manufacturing. However, only by allowing enterprises to deeply understand and master the characteristics and advantages of advanced technologies and products in various professional fields of informatization can informatization work become a supporting platform for enterprise product innovation.

At present, the automation level of CNC machine tools of many machine tool companies is not high, and data collection is difficult. The main problems include: some machine tools do not provide network interfaces and cannot be networked; networked machine tools can collect very limited data; CNC machine tool feedback programs are complex, etc. . The solution of these problems requires the further development and standardization of DNC, that is, the standardization of data acquisition signal output. These developments will play a revolutionary role in the development of MES (Manufacturing Execution Management System).

At present, domestic machine tool networking and data collection are in a period of rapid development. Compared with foreign products, there are some gaps in function and performance. However, domestic companies have greater advantages in services, especially in the face of enterprise application of machine tool equipment. In the current situation, the domestic DNC networking and collection can better meet the actual application requirements of enterprises.
