As sustainability becomes an important issue nowadays, disassembly becomes one of the key processes to turn out-of-service products into new or rebuilt products to save energy and materials. A disassembly process includes many subprocesses, such as separation, cleaning, and inspection. Features play a key role in design for disassembly and disassembly process planning. This paper describes a NIST-developed feature information model that defines generic form features, pattern features, and disassembly-specific features. The information model provides a foundation for computer-aided design for disassembly software systems development and data exchange among heterogeneous systems to integrate product design and disassembly process planning.
