Geometric Analysis of Casting Components

Automated manufacturability analysis, aiming to considerate manufacturability aspects at initial stages of product design, is important for the designers in modern manufacturing industry to design manufacturable components. It mainly assists designers to economize the cost and time without compromising the quality and functional requirements of manufacturable parts. This paper deals with feature recognition for automated manufacturability analysis of new casting product. A new region growing method and an octree-based wall thickness computation approach are developed to extract manufacturing features (such as cylinder holes and wall thickness), from a CAD model which is represented by STL format.
