| 摘 要： | IntroductionReverse engineering in the manufacturing fieldis a process that people first measure an existentobject model or a part to obtain its data,then re-construct its CAD model. The CAD model repre-sents the geometric features and other propertiesoforiginal object and also can be used for many otherpurposes,such as analysis,modification,manu-facturing and test etc.The main difference be-tween conventional forward engineering and re-verse engineering is that the former is an explicitphys…

| Abstract: | This paper presented a model of integrated reverse engineering system and set up its various data output flowchart, which is easy to be associated with other systems. The idea of integrated reverse engineer is introduced to the system of forming sheet metal with complex surface and using IDEF0 method sets up the function model of the system. The freeform surface reconstruction and CAD modeling of the system are described and decomposed. This paper discussed some problems, such as the feature expression, feature modeling and feature translation of the sheet parts and dies. |
