concurrent consideration
1.From the angle of the concurrent engineering,the authors establish a hierarchic architecture model for the concurrent CAPP system. In the technological design of the concurrent process planning system its integration is taken into consideration with upper level(CAD) and bottom level (PPS). It simulates hierarchic principle of design in the manual process planning.
2.The Design For Manufacture (DFM) is an important enabling technology in Concurrent Engineering, which assures product design, process design and manufacturing could be succeed at one time by taking the factors associated with manufacturing into consideration in the phase of design;
