The present invention relates to a numerical control machine tool digital twinning modeling method. A physical space, a digital twinning digital space and a digital twinning mapping model are provided. The digital twinning digital space is connected with the physical space through the digital twinning mapping model; a data sensor is installed on a numerical control machine tool, the data sensor isconnected with a numerical control system through different data interfaces, the numerical control system performs related data collection and protocol analysis through the digital twinning mapping model; the digital twinning digital space comprises a digital twinning description model and a digital twinning intelligent model, and the digital twinning intelligent model achieves intelligent service of numerical control machine tool digital twinning through data analysis and decision. The modeling method employs multi-field uniform modeling language Modelica to allow the established digital twinning description model to have features of multi-field uniform modeling, mathematics equations and object-orientation, and can more really reflect the constitutive relation of a complex dynamo-electric system.
Description
technical field [0001] The invention relates to a digital twin modeling method of a numerically controlled machine tool, in particular to a multi-field, object-oriented, and component-based modeling method of a digital model of a machine tool, and belongs to the technical field of equipment intelligence and digitization. Background technique [0002] Machine tool is the mother machine of the manufacturing system, the foundation of the manufacturing industry, and an important symbol of the strength of the country. However, the level of intelligence and digitalization of CNC machine tools is still relatively low. The implementation of "Industry 4.0" and "Made in China 2025" requires the support of digitization and intelligence of manufacturing equipment. How to improve the intelligence and digitalization level of CNC machine tools under the background of the integration of industrialization and informationization under the guidance of its advanced concepts is a key issue in i...
