Problems solved by technology
However, the traditional CNC machining technology has inherent deficiencies: it does not consider the complex state changes in the machining process accompanied by workpiece material removal, resulting in the inability to deal with the "emergency" situation in the machining process in real time and take effective measures. Countermeasures, which limit the processing performance of CNC machining, it is difficult to guarantee the processing quality of parts
Although some studies have reported the potential application prospects of digital twins in manufacturing, the current methods of realizing digital twins in the manufacturing field lack an in-depth understanding of the concept, framework and development methods of digital twins, which hinders the application of digital twins in smart manufacturing. development of

The digital twinning representability modeling system for a manufacturing full life cycle is characterized in that the digital twinning representability modeling system comprises a product physical object belonging to actual production; an associated virtual object generated by a digital twinning modeling system which is a twinning object; a transmission layer which is used for sensing and feedback; the twinning object comprises a digital twinning reference model, and the digital twinning reference model is further divided into an information model and a decision model; a mimicry perception layer is arranged between the physical object and the twinning object, related information is obtained through the mimicry perception layer, an information model of a product virtual object is generated, analysis and decision making are carried out through a decision making model, and the physical object is fed back and controlled through the transmission layer. On one hand, intelligence of the numerical control machining system is achieved, and on the other hand, the manufacturing physical world and the information world are interconnected and fused.
Description
technical field [0001] The invention relates to the technical field of intelligent manufacturing, in particular to a digital twin expressive modeling system oriented to the whole life cycle of manufacturing. Background technique [0002] NC machining technology shows good operability, adaptability and repeatability in solving machining problems, and has always been the main method and means of machining. However, the traditional CNC machining technology has inherent deficiencies: it does not consider the complex state changes in the machining process accompanied by workpiece material removal, resulting in the inability to deal with the "emergency" situation in the machining process in real time and take effective measures. Countermeasures, which limit the processing performance of CNC machining, it is difficult to guarantee the processing quality of parts. At the same time, the cutting process involves relevant knowledge and theories of physics, chemistry, mechanics, materi...
