Framework of 3D Model Manufacturing Features Extraction Technology

Abstract

This paper proposes a new feature recognition framework based on extensible rules, dividing recognition into two steps of extraction of model information and matching manufacturing features. The model information contains geometrical information and non-geometrical information. A new concept of mate rule and a neutral platform are introduced in matching of manufacturing features. Matching templates are established by combining mate rules in the neutral platform. Manufacturing features are recognized by matching geometrical information with templates. Attributes of manufacturing features are obtained from restructured non-geometrical information. The process and result of recognition is represented through a shaft part.
