The Modeling Method of Digital Twin Models for Machining Parts

This paper introduces digital twin models for machining parts based on key features and gives the modeling method. In this paper we propose three layers structure of the digital twin model, including geometric layer, data layer and document layer, in order to make machining process optimization and quality prediction. The digital twin model realizes the expression of physical parts in digital space and the information correlation with theoretical processing features. Besides, this paper also analyzes the potential application scenarios and development trends of digital twin models of machined parts.
