3-Dimensional Model using Feature Recognition Rules from Orthographic Views for CAD/CAM Interface

CAD/CAM 인터페이스를 위한 정사영도면의 형상인식을 이용한 3차원 모델링

As a basic step of interfacing CAD and CAM, it is required to convert thedrawing data into manufacturing information automatically. In this study the developed system carries out feature recognition from the orthographic views of press mold containing various pockets. Using rhe recognized output data, 3 dimension- al model is built using ADS and AME in order to check the result of recognition. The system consists of 4 main parts, suchas, Preprocessing, Coordinate handling, Feature recognition and 3D-modeling. The system shows a good application example which can interface the design and manufacturing stage in CAD/CAM system on PC level
