A Manufacturing Feature Extraction System in Machining Process Planning


Keita Takahashi, Hendry Litou


Vol. 14  No. 3  pp. 25-33


Manufacturing feature can be applied as an intelligent interface that can understand the meanings of the product design information preserved in CAD (Computer Aided Design) data from the view point of manufacturing technology. Thus, the establishment of a manufacturing feature extraction system that has the ability to extract suitable manufacturing method effectively from the design objects is essential in developing a CAPP (Computer Aided Process Planning) system. Considering the role of manufacturing features in process planning, it is necessary to develop a manufacturing feature extraction system that is able to extract manufacturing feature, which is not only the geometric shape, but also the corresponding manufacturing information to create the intended shape. In this paper, a manufacturing feature extraction system is proposed. A case study is used to show the validity of the proposed system
