Abstract :
Current CAD system represents part by set of vertices, lines face and/or volume. This type of presentation is not suitable for most manufacturing application such as Computer Aided Process Planning (CAPP). At manufacturing level, decisions are mainly based on higher entities, which are commonly called manufacturing features. This paper describes the development of STEP Hole Recognition System called S_HoRS for CAPP. S_HoRS will convert geometrical data specifically holes from the STandard for the Exchange of Product model data (STEP) file into feature based model suitable for process planning activities, especially for tool and die components. Rule-based algorithm is used for the recognising process. The output from S_HoRS is the hole’s feature data such as radius, height and the coordinates system. Current implementation of the S_HoRS is limited to simple hole features
