数控机床数字孪生标准体系研究

Research on digital twin standards system of CNC machine tool

数字孪生作为推动智能制造的关键使能技术,如何在机床领域落地应用成为备受关注的焦点。然而,数控机床数字孪生术语、架构、关键技术等相关标准的缺乏,严重阻碍了数字孪生技术在数控机床领域的推广应用。为解决上述问题,亟需制定数控机床数字孪生标准给予参考和指导。因此,首先分析了数控机床数字孪生标准的需求,在此基础上,结合数字孪生五维模型和前期对数字孪生技术的研究,构建了数控机床数字孪生标准体系框架,该标准体系主要包括通用、安全、测评等基础共性标准和数控机床配置、数字孪生建模、数据处理、连接交互、集成与服务等关键技术标准,并对数控机床数字孪生标准的应用与定位进行了分析讨论。期望相关工作能为数控机床标准及数字孪生标准研究与制定人员提供参考,同时为数字孪生技术在数控机床领域的落地应用提供指导。

As a key enabling technology to promote the development of intelligent manufacturing, digital twin is drawing great attention on applying in the field of CNC machine tool. However, the lack of general and fundamental standards such as technical terms, reference architecture, key technology leads to problems of application in the field of CNC machine tool. Therefore, digital twin standards of CNC machine tool are urgently required. This study analyses the demand of digital twin standards of CNC machine tool.Based on the above research, combined with five-dimension on digital twin model and research on digital twin technology, this study constructs the framework of digital twin standard system of CNC machine tool, which contains fundamental standards such as general requirements, safety, test methods and key technology standards such as CNC machine tool configuration, data processing, connection and interaction. Discussion is done on the application and function of digital twin standards of CNC machine tool. Hope this work can not only give reference for researchers of digital twin standards and CNC machine tool standards, but also guide for digital twin application in the field of CNC machine tool.
