In the context of Industry 4.0 and “Internet+â€, new changes have taken place in the future development and competition of CNC systems. More competition in China will focus on how to use the advantages of the Internet and allow the CNC system's computing capabilities to be infinitely expanded. , And through the understanding of the emerging business models such as sharing the economy, rationally building the appropriate functions becomes an important trend in the future.
1. CNC system intelligent requirements
The need for intelligentized CNC machine tools
From the point of view of manufacturing technology itself, the intelligentization of CNC systems is carried out in four aspects as shown in Figure 4: Operational Intelligence, Process Intelligence, Maintenance Intelligence, and Management Intelligence.
Through the use of various sensors in the machining process, the machine tool can further improve the performance of the machine tool with real-time monitoring and compensation technology. Companies such as Mazak and Otsuka have provided many advanced technologies in terms of intelligence, such as spindle vibration suppression and smart anti-collision. Shenyang Machine Tool i5 CNC provides feature-based programming and graphical diagnostics.
2. Cloud-based CNC systemOn the basis of cloud computing, the University of Stuttgart in Germany put forward a "glocalized" cloud-based numerical control system. The concept is shown in Figure 5. From the figure, it can be seen that the human-machine interface, numerical control core, and PLC of the traditional numerical control system have been moved to. In the cloud, only the servo drive and security control of the machine tool are retained locally, and communication modules, middleware, and Ethernet interfaces are added in the cloud, and the local CNC system is communicated through the router. In this way, the “Digital Twin†of each machine in the cloud can be configured, optimized and maintained in the cloud, which greatly facilitates the use of the machine. Implementing a so-called controller as a service CaaS (Control as a Service).
Cloud CNC concept
Digital hygiene refers to the digital mirroring of a specific physical object, including design specifications and engineering models that describe its geometry, materials, components, and behavior, as well as production and operational data specific to the entity it represents, becoming inseparable “partners†that are physical object attributes. The latest and accurate real-time images of states and states, including shape, position, state, and motion. The digital twin of a machine tool can exist in multiple information domains at the same time. There are multiple “avatarsâ€. In the product design phase, they assume the role of program verification, structure and function verification, and optimization of performance parameters. They participate in the layout planning during the planning stage of the construction plant. The system optimizes the simulation and other work; during the operation phase, the processing status is judged and predicted, and the intelligent control and preventive maintenance of the machine tool are realized until the end of the product scrapping, even after that.
3. Internet CNC system and its ecosystemUnder the conditions of the Internet, the CNC system must become a transparent intelligent terminal capable of generating data, allowing the manufacturing process and its entire lifecycle to be “data transparentâ€. Through the “transparency†of the intelligent terminal, the transparency of the manufacturing process is realized, not only facilitating the processing of parts, but also producing real-time data for management, finance, production, and sales, realizing equipment, production planning, design, manufacturing, supply chain, manpower, Integration of resources and information in a series of production and management links such as finance, sales, and inventory.
The Shenyang Machine Tool Group has established a machine tool ecosystem around the i5 intelligent machine tool in the world. Figure 6 is a schematic diagram of the i5 intelligent machine tool on data generation and application. Through the “transparent†i5 intelligent system, the i5 intelligent machine tool can be online in real time. The management process provides accurate data evidence and forms the basis of the new manufacturing state.

Intelligent Machine Tool Internet Application Framework Based on iSESOL
iSESOL (i-Smart Engineering & Services Online) is a cloud manufacturing platform developed by Shenyang Machine Tool's company, such as a cloud-based capacity sharing platform. Users can display idle production capacity on the iSESOL productivity platform. Users with capacity needs can quickly acquire equipment without purchasing equipment. Gaining manufacturing capacity, in this way, capacity suppliers can use idle capacity to gain revenues, capacity demanders can gain manufacturing capacity at lower cost, and both parties can maximize profits through sharing.Undoubtedly, this model will become the manufacturing industry’s Internet. An important form of +.
The picture above shows the intelligent machine tool internet application framework based on the iSESOL platform. All i5 smart devices access the iSESOL network through the iPort protocol. Non-i5 devices (such as OPC UA terminals or MTConnect terminals) can access the iSESOL network through the iPort gateway. Applications in the cloud such as ERP, MES, and remote kanbans achieve unified access to remote devices through iSESOL aggregated real-time data and access interfaces. iSESOL provides data dictionary mapping for different devices to unify the access methods of different devices. The cloud APP can subscribe to all kinds of events and data information and achieve unified device access by simply naming standard services or parameters. End-users can implement various Internet applications for devices through different terminal installation APPs. The capacity-building collaborative ecosystem established under this platform has now connected thousands of machine tools, and currently has about 2,500 online connections.
The intelligentization and networking of the machine tool numerical control system is the general trend. The concept of CPS is used to guide the development of the intelligent numerical control system. Through the network and platform, the intelligentization of the numerical control machine tool is realized from the perspective of the entire system.
The development of intelligence is a step-by-step process. At present, there are different understandings of intelligence and there is no universally applicable solution. The innovation and real operation of the CNC machine tool business model must rely on the intelligentization and networking of the CNC system. The future CNC system will increasingly penetrate the influence of the Internet into the manufacturing process. Through the accumulation, transmission, and mining of data, more and more intelligent manufacturing capabilities will be born, and transparency and sharing will be used for manufacturing. The industry brought about earth-shaking changes.
