System Integrated Framework of Die &Mold CAD Based on Concurrent Engineering

Based on the theory technology of system integration,the relationship matrix between design process and information was established by analysis of design information exchange distribution princi- ples.The concurrentdesign framework for progressive die was also set up.The key processes of concur- rentdesign were determined.Based on the above methods,concurrent engineering- based CAD system in- tegration framework of progressive die was summed up,and this framework was furtherabstracted to cre- ate a general CAD system integration framework for die mold concurrentdesign.As the description for the deploymentof concurrentengineering in die mold design and manufacturing,the lastframework can serve asa guide orreference both in theory and methodologies forimplementing the concurrentengineering in many kinds of die and mold design and manufacturing.
