With the rapid development of a new generation of artificial intelligence technology and information and communication technology,the traditional manufacturing industry has started to transform into technology-based intelligent manufacturing.Digital twin technology is a key technology to realize intelligent manufacturing,which can effectively solve the problem of difficult information transmission in the transformation of manufacturing industry.Developed a virtual simulation monitoring system for gantry milling machine tool machining process based on digital twin technology.Based on the traditional virtual simulation monitoring system,the motion simulation of gantry milling machine in the process of machining is realized,and the visual chart is introduced to show the motion speed of each axis of gantry milling machine.The three-dimensional modeling of machine tool is carried out by using SolidWorks software according to the ratio of 1∶1.Import the created model into 3Ds MAX,add materials to the model and convert the format of the model.Then import the model into Unity,and set up a workshop scenario in Unity.The virtual simulation of the whole machining process of machine tool is completed through the script.The script was written to complete the virtual simulation of the whole machining process of gantry milling machine,and the Xcharts plug-in based on UGUI was used to draw the visual chart.The results show that the system can simulate the motion of each axis in the gantry milling process,and display the real-time speed of each axis of the gantry milling through visual charts,which can provide certain technical support and reference for the development of similar systems.
