| Abstract: | A design model for parts generation using feature-based information moddlling has beenworked out.By means of the automatic extraction of the processing features and the sum-ming up of manufacturing decision knowledge,a cornputer-aided process planning system forsheet metal bending with the Petri net for modelling has been developed.As a link betweenCAD and CAM,this system can automatically generate bending procedures according to theinput parts drawings and carry out computer simulation. |
