External economic risks make people aware of the disadvantages of deindustrialization. "Return to manufacturing" is the development strategy of many developed countries. Manufacturing must not only be revitalized, but also developed with high quality. We talked about intelligent manufacturing today, and its industrial chain covers intelligent equipment, industrial Internet, industrial software, 3D printing and so on. Intelligent equipment also includes robots, CNC machine tools, and other automation equipment. Machine tools are the "workhorses" of modern manufacturing, and they are a measure of the level of industry in a country or region.

Intelligent manufacturing is a hot topic in the industry. What is intelligent manufacturing? In layman's terms, it is to make machines and equipment closer to the function of the human brain, and to be able to autonomously deal with problems in production. Under the trend of intelligent manufacturing, what is the development trend of machine tools as "working mother machines"? We all know that the CNC system is the "brain" of the machine tool and the core technology for the transformation and upgrading of the manufacturing industry. From a certain perspective, the development of intelligent manufacturing in the future cannot be achieved without breakthroughs in numerical control systems and key technologies. Below, I will take a few cases at home and abroad to see how to upgrade the technology of machine tools at home and abroad in the context of intelligent manufacturing.

MAZAK's SMOOTH technology

MAZAK's intelligent machine tools and systems combine high-speed and high-precision processing with the needs of the current Internet of Things era. In terms of human operation experience and progress management, richer intelligent functions have been added. For example, turning table balance sensing function, thermal displacement control function, interference prevention function, anti-vibration control function, navigation function, fine adjustment of processing parameters, etc. These functions have achieved a significant improvement in the production efficiency of the machine tool.

DMG

DMG MORI and Schaeffler jointly develop the intelligent machine tool DMC80FD through the "Machine 4.0" innovation project. The main feature of this machine tool is that more than 60 sensors are installed at key components to record vibration, stress and large temperature data during processing. At the same time, the corresponding system has also developed an APP to realize the status monitoring and evaluation of machine tools, as well as the functions of machine tool applications.

Central China iNC Intelligent CNC System

Huazhong NC launched this iNC system. Based on the real-time operating conditions and status information of NC machining, the intelligent control strategy and knowledge obtained through independent learning are used to form a multi-objective optimized machining intelligent control "i-code" to achieve autonomous Decision function. In addition, it also includes autonomous execution, autonomous perception, and autonomous learning functions.

i5 smart machine

We do not look at the business model of Shenyang Machine Tool, but it has made some explorations and practices in terms of intelligent manufacturing. i5 refers to the effective integration of industrialization, informationization, networking, intelligence, and integration.

The i5 intelligent machine tool has the characteristics of intelligent compensation, intelligent diagnosis, intelligent control, and intelligent management, and realizes high-precision, high-efficiency, low-energy-consumption processing. The machine's unique Internet function makes it a smart terminal, enabling distributed, hierarchical, and shared manufacturing.

Three key technologies

From the above four cases, it is found that CNC machine tools are increasingly emphasizing intelligence and digitization, which is reflected in the data collection of machine tool components and the realization of functions such as autonomous monitoring, analysis, diagnosis, and control. To this end, we will find the future development of CNC machine tools: firstly, the increasing application of sensor technology; secondly, the integration of network technology and numerically controlled machine tools; and thirdly, the intelligent functions of machine tools have been presented from initial to rich and perfect.

It can be seen from the development trend that the three key technologies of the future intelligent CNC machine tools are: information perception and data processing, that is, self-learning, self-adaptation, liberalization control, and common interfaces and protocols; , Monitoring, error compensation and other technologies; the third is the digital twin technology centered around CNC machine tools.
