Future Prospects of Nonstandard Automation Equipment Intelli

Edit::2019-09-18 10:37
In the context of automation equipment industry 4.0 and "Internet +", the future development and competition of CNC systems have undergone new reforms. More competition in China will focus on how to take advantages of the Internet to make the computing ability of CNC systems available, and to forge corresponding functions through the understanding of emerging business models such as the sharing economy.
 
1. CNC system intelligent requirements
The intelligent needs of CNC machine tools
From the perspective of manufacturing technology itself, the intelligent of the numerical control system is carried out in four aspects: intelligent operation, non-standard automation of processing, intelligent maintenance and intelligent management.
The machine tool further improves the performance of the machine by using various sensors and real-time monitoring and compensation technology during the processing. Companies such as Mazak and Daxie in Japan have provided many advanced technologies in intelligence, such as spindle vibration suppression and intelligent anti-collision. Shenyang machine tool i5 CNC provides functions such as feature-based programming and graphical diagnostics.
 
2. Cloud platform-based CNC system
On the basis of cloud computing, the University of Stuttgart in Germany proposed the “global localization (glocalized)” cloud numerical control system. The human-machine interface, CNC core and PLC of the traditional CNC system are moved to the cloud, the local only saves the servo drive and security control of the machine tool. In the cloud, the communication module, middleware and Ethernet interface are added, and  communicate with the local CNC system through the router. In this way, there is a “Digital Twin” for every machine in the cloud, and the machine can be configured, optimized and maintained in the cloud, which greatly facilitates the use of the machine.
 
Cloud CNC system concept
 
Digital twin refers to the digital image of a specific physical object, including design specifications and engineering models describing its geometry, materials, components and behaviors, as well as unique production and operational data. The digital twin of machine tools can exist in multiple information domains at the same time and has multiple “avatars”, which play the role of program demonstration, structure and function verification and performance parameter optimization in the product design stage; participation in the layout planning and system optimization simulation during the planning phase of the plant construction; prediction and judgement of processing state during running stage to achieve the intelligent control and predictive maintenance of machine tool until the product scrapping.
 
3. Internet CNC system and its ecosystem
 
 The development of intelligence is a gradual process. At present, there are different understandings of intelligence, and there is no universally applicable solution. The innovation and implement of the CNC machine tool business model need to rely on the intelligence and network of CNC system. In the future, CNC systems 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 bring earth-shaking changes to manufacturing industry.
