What Are Development Trends of CNC?

The application of computerized numerical control technology not only brought revolutionary changes to the traditional manufacturing industry, but also made the manufacturing industry a symbol of industrialization. With the continuous development of numerical control technology and the expansion of application fields, it plays an important role in the development of some important industries of the national economy and the people's livelihood.The digitization of the equipment required in these industries is a major trend in modern development. From the trend of numerical control technology and its equipment development, the development trend of numerical control technology is as follows:

Five-axis simultaneous machining and rapid processing of machine tools

The 5-axis joint machining of the 3D curved parts can be performed with the best geometry of the tool, which not only has a high finish, but also greatly improves the efficiency. It is generally believed that the efficiency of one 5-axis linkage machine tool can be equal to two 3-axis linkage machine tools, and the 5-axis linkage machining can achieve higher efficiency than the 3-axis linkage machining. However, in the past, due to the 5-axis linkage CNC system and the complicated structure of the mainframe, the price was several times higher than that of the 3-axis linkage CNC machine tool. In addition, the programming technique was difficult, which restricted the development of the 5-axis linkage machine tool.

At present, due to the emergence of the electric spindle, the structure of the composite spindle head for 5-axis simultaneous machining is greatly simplified, the manufacturing difficulty and cost are greatly reduced, and the price gap of the numerical control system is narrowed. Therefore, the development of the composite spindle head type 5-axis linkage machine tool and the composite machining machine tool has been promoted.

Intelligent, open and networked become the main trend of the development of CNC systems

The 21st century CNC equipment will be a system with certain intelligence. The intelligent content is included in all aspects of the CNC system: for the pursuit of processing efficiency and processing quality, such as adaptive control of the process, automatic process parameters generate.

In order to improve the driving performance and use the connection intelligent, such as feedforward control, adaptive calculation of motor parameters, automatic identification of load automatic selection model, self-tuning, etc.; it simplifies the intelligentization of programming and operation, such as intelligent Automatic programming, intelligent human-machine interface, etc.; as well as intelligent diagnosis, intelligent monitoring content, convenient system diagnosis and maintenance. In order to solve the problems of the traditional CNC system closure and the industrial production of CNC application software.

The network of CNC equipment will greatly meet the demand for information integration in production lines, manufacturing systems, and manufacturing enterprises. It is also the basic unit for implementing new manufacturing models such as agile manufacturing, virtual enterprise, and global manufacturing. The core of current numerical control technology research lies in the architecture specification, communication and configuration specifications, operation platform, numerical control system function library and numerical control system function software tools of open CNC system.
