基于范例的推理, 实例修改, 焊接管件, 夹具设计

 ,

Owing to a lot similarities in the welding tube,the CBR method was applied into the welding tube flexibile fixture design herein.The feature of workpiece and fixture were considered in the case similarity.The design rules and coordinate transforming technique with the secondary development technology based on Solid Edge were used to modify the case in order to assemble automatically. The application of the algorithm based on the knowledge in the retrieve of the similar cases,the strategy of case adaptation and case storage, improves highly the reuse of design knowledge, decreases repetitive work and solves the problem which the intelligence level of the fixture redesign in new case is not high.
