Research on Digital Engineering Modeling System under Computer Virtual Reality Technology

This paper deeply understands the functional modules of the VERICUT software system and the NX software modeling technology based on the computer virtual reality technology of CNC machine tool engineering. Then this paper uses three-dimensional software to build the measured size model of machine tool engineering, and builds the virtual simulation environment of the machine tool in the numerical control virtual simulation processing software VERICUT. Then this paper obtains the parameters of the virtual material model of the joint based on the multi-objective optimization method, and builds an accurate virtual material model of the joint. In this way, an accurate dynamic model of the CNC machine tool is established. The system realizes the information exchange between the machine tool simulation controller and the model, and supports the virtual debugging function of the model. The simulation results show that the method is feasible and can effectively improve the virtual-real interaction ability, data visualization degree and state monitoring efficiency of machine tools.
