Automated Reference Model Generation and Utilization for Dimensional Control of Large Scale Assemblies and Assembly Processes

摘要

A lot of manual user interaction with computer aided design and analysis software is currently needed for dimensional control of large scale assemblies. This user input is required for both selecting the vital entities to be measured and analyzing the results of the measurements. In this paper an automated approach for reference model generation and vital entity selection is presented. The reference model generation is guided by user editable knowledge base and it is based on data extraction from computer aided design data. Prospects to utilize the generated reference model for automated manufacturing accuracy analysis are also outlined. The software implementation made has proved to be feasible for different kinds of dimensional control needs of large scale assemblies, and outweighs the current state of the art both in speed, completeness, and versatility.
