Design And Implemention Of Digital Twin Web Platform For Milling Process

The traditional simulation method can not reflect the real process because there is no information exchange between the simulation and the real process.Digital twin technology is an important development direction of intelligent manufacturing.The digital twin can reflect the real milling process in virtual space by synchronizing datas from milling process.So the digital twin can verify the rationality of the milling process and reduce the abnormalities in the actual process.However,deploy a digital twin is complex and time comsuming and the depolied digital twin is always expensive hardware to access.So a digital twin web platform for the milling process,which can depoly the digital twin for milling process quickly and drives it with real-time dates,is designed and developed.The main work of this dissertation has the following aspects:1.This dissertation analysis the requirement of the platform,designs the framework and functional modules of the digital twin web platform.2.This dissertation researches the key technologies for platform development and implementation.A digital twin information model for the milling process is designed to address the data mapping and exchange problem between the digital twin model and the actual milling process.A milling process material removal simulation algorithm is studied to address the 3D display problem of material removal process.A data communication architecture of the platform is designed to realize data communication.3.This dissertation realizes and develops the digital twin web platform.The user interface is realized by Axure software.The key functions such as 3D model rendering,virtual scene construction,geometric transformation and animation are developed.The material removal simulation module is developed by Opencascade technology.The data communication module is developed.This dissertation validates and tests the performance by a case study.The results shows that the developed platform can run the digital twin stably and smoothly.The developed digital twin web platform can meet the design goal.
