Assembly semantics modeling for assembling process planning in virtual environment

Purpose - The purpose of this paper is to develop a modeling and interactive operating method for virtual assembly (VA) to support assembly process generation based on interactive operation. Design/methodology/approach - This paper puts forward an assembly semantic modeling method for interactive assembly and process generation after the analysis on requirements of operation process generation. Based on this semantic model, methods for semantic generation, semantic processing and assembly motion extraction from interactive operation are presented. Partial process generation of auto engine is proposed to verify the approaches in this paper. Findings - The application shows that assembly semantic modeling and operating methods can support process generation based on VA operations. Originality/value - The approaches presented in this paper improve the efficiency of assembly process, making assembly process intuitive and natural.
