The key to intelligent manufacturing lies in the information of CNC machine tools. interact. However, CNC machine tools are multi-source heterogeneous systems with great differences, which brings difficulties to information interaction and also forms the above-mentioned problems. The bottleneck of the interaction between the layer application system and the CNC machine tool. To this end, smart factories need a unified and standardized CNC machine tool interconnection protocol, the core of which is the interconnection model and interface specification. At present, some CNC equipment interconnection standards or protocols have been proposed at home and abroad, but these standards and protocols cannot meet the needs of digital twins. Data requirements, for this reason, according to the needs and development trends of domestic industrial interconnection, relevant interfaces that meet the interconnection of CNC machine tools in smart factories should be formulated specification. It is against this background that the Smart Factory CNC Machine Tool Interconnection Interface Specification (NC-Link for short) was proposed and formulated. NC-Link is used to connect Connect the CNC machine tool with the application system, transmit the attribute data, parameters and operation information of the CNC machine tool to the application system or control the application system The information is transmitted to the CNC machine tool to realize information interaction. In addition, when the CNC machine tools of the smart factory are interconnected, they also need to collect and use other The data of the auxiliary equipment of CNC machine tools such as measurement and logistics, so the interconnection interface of CNC machine tools in the smart factory will also cover the data of these auxiliary equipment interface. Smart factory CNC machine tool interconnection interface specification1 ScopeThis document specifies the interconnection interface specifications of CNC machine tools in smart factories (hereinafter referred to as NC-Link), including general requirements, CNC machine tool models Definition, data item definition, data transmission interface definition and testing and evaluation. This document applies to CNC machine tools and their ancillary equipment. Other digital equipment in the smart factory can be used as a reference.2 Normative referencesThe contents of the following documents constitute the essential provisions of this document through normative references in the text.

GB/T 25069-2010 Information Security Technical Terms3 Terms and DefinitionsThe following terms and definitions defined in GB/T 25069-2010 apply to this document. 3.1 application system application system Software and hardware for analyzing, managing and monitoring the attribute data, parameter data and operation data of CNC machine tools or controlling CNC machine tools file system. Note. Common application systems include ERP, MES, etc. 3.2 adapter adapter Software components or hardware devices, used to connect the agent and the CNC machine tool to realize the collection of attribute data, parameter data or Run the data and perform format parsing and conversion, transmit it to the agent in a unified format, or receive control information from the agent, and follow the instructions The specified CNC machine tool needs to be converted and transferred to the corresponding CNC machine tool. Note. Since there is a one-to-one correspondence between the CNC machine tool and the adapter, the adapter is used in this document to represent the CNC machine tool. 3.3 agent agent A software component or hardware device used to connect the adapter and the application system to collect data from the adapter and distribute it to the application system, or Receive the control information from the application system and download it to the adapter. 3.4 terminal terminal Application system or CNC machine with adapter connected. NOTE. Terminals are identified by a unique terminal identifier within the system. ......Tips & Frequently Asked Questions:Question 1: How long will the true-PDF of GB/T 41970-2022_English be delivered?Answer: Upon your order, we will start to translate GB/T 41970-2022_English as soon as possible, and keep you informed of the progress.
