Intelligent extrusion die design based on knowledge graph

Abstract

Aluminium profiles have an increasing demand since its excellent physical properties. At the same time, the crosssection shape of the profile is becoming more and more complex, which makes the design of its extrusion die more difficult and time consuming. To fill this gap, this paper has proposed an intelligent design method based on capturing and reusing the design knowledge of the extrusion die. Specifically, a knowledge representation model is created to reveal the key design knowledge generated during the design process. Then, a multi-modal knowledge graph is built to systematically structure and store the design information and knowledge. Finally, a smart design system is developed for the application of knowledge capturing and rueing by semantic retrieval and intelligent recommendation. Through applying and evaluating in a leading aluminium profile enterprise, this method has shown its ability in helping engineering designer in design knowledge reuse and improving design efficiency.
