面向数字化及服务化的新一代信息物理机床

随着信息物理系统、物联网、云计算等信息与通信技术的蓬勃发展，新一代工业革命即工业4.0的到来已形成广泛共识。在这种“智能制造”的大环境下，机床作为制造系统的核心装备，急需进行面向数字化及服务化的技术革命，以适应并推进新型智能制造系统如信息物理生产系统、智慧工厂等的发展。当前，阻碍机床数字化及服务化的主要问题包括较差的机床数据连接性与互操作性、现场级智能数据分析能力的不足以及缺乏面向服务化的发展模式等。信息物理机床概念的提出为机床的数字化及服务化提供了一个有前景的解决方案。本项目针对信息物理机床的理论基础与实际应用进行深入研究。主要的创新点包括：1）多维度机床数字孪生体的理论建模方法；2）基于边缘-云架构的互操作性信息物理机床平台；以及3）基于模块化智能算法的定制化智能制造服务。本项目的预期成果将为面向数字化及服务化的新一代信息物理机床提供坚实的理论基础以及可展示的实际应用范例。

With the rapid development of information and communication technology such as Cyber-Physical Systems, Internet of Things, and cloud computing, the arrival of a new industrial revolution, namely Industry 4.0, has been widely recognized. In this "smart manufacturing" environment, machine tools, as the core equipment of any manufacturing system, are in an urgent need for a technological revolution of digitalization and servitization, such that they can adapt to and facilitate the development of the envisioned smart manufacturing systems such as Cyber-Physical Production System, Smart Factory, etc. At present, the main problems that hinder the digitalization and servitization of machine tools include poor data connectivity and interoperability, the lack of field-level intelligent data analytics and the lack of service-oriented development method. The concept of Cyber-Physical Machine Tool (CPMT) provides a promising solution for the digitalization and servitization of machine tools. This project is an in-depth study on the theoretical basis as well as the practical application of CPMT. The main scientific contributions include: 1) a theoretical modelling methodology of multidimensional machine tool digital twin, 2) an edge-cloud architecture-based interoperable CPMT platform, and 3) customizable intelligent manufacturing services enabled by modular intelligent algorithms. The expected results of this project will provide a solid theoretical foundation as well as demonstrative application examples for the next-generation CPMT towards digitalization and servitization of manufacturing.
