Feature-based integrated concurrent engineering design for next-generation CAD systems

摘要

Abstract: To address the need for producing high quality designs with better life-cycle performance and shorter product development lead-times, the methods for developing new CAD systems that support integrated concurrent engineering design are studied. A feature-based, integrated concurrent design model, and associated software structure are proposed. In this prototype system, a design is modeled using features from the three most important perspectives of a mechanical product: design, manufacturing and geometry. A hybrid database scheme has been developed for representing the qualitative and quantitative information of these models. The methods for identifying the most cost-effective design and optimal concurrent design are illustrated using examples.!14
