Conventionally, product and process development activities were performed separately and sequentially by designers and engineers with different responsibilities and expertise. Due to lack of communication among the development activities, a product may be designed quite sophistically but not manufacturable or too costly. In recent years, the concept of concurrent engineering has been proposed to overcome this problem by resolving all life cycle issues at the early design and current computer-aided design. The objective of this research is to develop a systematic and concurrent injection molding product design methodology and procedure that enable the practice of concurrent product design. A computer-based concurrent injection molding product design framework is then proposed based on this methodology. According to this framework, a feature-based design for injection molding system is developed using knowledge-based approach and object- oriented methodology. This system provides a feature-based injection molding product design tool and a moldability assessment tool to help the concurrent consideration of product quality and manufacturability in product design. The results of this research will facilitate the rationalization, concurrentization and computerization of product design and consequently improve the effectiveness of product and process development.EndProc
