Considering Designer’s Intention for the Extraction of Manufacturing Feature

A manufacturing feature can be defined simply as a geometric shape and its manufacturing information to create the shape. For the extraction of manufacturing features with their proper manufacturing information from the product design information, it is needed to consider the designer’s intention described in the functional data of the face elements that construct the manufacturing features. In this paper, a new manufacturing feature ontology is proposed. New subclasses of manufacturing features are created based on the required manufacturing method to create the shape of the manufacturing features as intended by the designer. By developing a feature library based on the proposed manufacturing feature ontology, the extraction of manufacturing features with their proper manufacturing information is made possible.
