Abstract: Computer Aided Process Planning (CAPP) provides a link between design and manufacturing in a Computer-Integrated Manufacturing (CIM) environment. The Automatic Feature Recognition (AFR) plays a significant role in the contribution of Computer Aided Design and Computer Aided Manufacturing (CAD/CAM) integration. In this paper, an object oriented approach is applied to prepare the part geometric database from a neutral file (STEP AP 203) and translates this information to manufacturing knowledge. The algorithms and rules are then formulated to extract, group and recognise the form feature and their dimensions. The feature based CAPP system is then produced along with the setup plan using machining database and an algorithm based on feature location. The proposed methodology is tested by using a case study.
