Thispaper desicribes an integrated CAD/CAPP system which is implemented by connecting MPIM to BR-CAPP via an interface for data exchange between them. The data exchange between MPIM and BR-CAPP is accomplished through STEP neutral file.展开更多

A STEP based feature technology in which a three layer feature definition is included is discussed, the content of feature information is analyzed and a stratified CAD feature library is shown. On these bases, a commonly shared part information model is proposed. The architecture of the integrated CAD/CAPP system is presented.展开更多
