Process Planning System for Body In White Based on Data Mining

To improve the efficiency of process planning for Body In White(BIW),data mining technology is applied to capture useful process information.Manufacturing resource database,process principle database and process example database are built respectively.Reasoning system based on data mining is constructed.Semantic matching method is used to query parts and welding robots.The association rules are used to select the most reasonable welding type.The Genetic Algorithm(GA) is used to optimize welding path.Application results show the system can manage process information for BIW effectively.
