An Intelligent Feature-Based Design for Stamping System

In this paper, an intelligent feature-based DFS (design for stamping) system has been proposed for implementing the stampability evaluation. The work includes identification of the aims, criteria, and procedure of stampability evaluation, as well as the formalisation of the stampability evaluation knowledge. The stampability evaluation has been oriented to part shape analysis and cost estimation, based on features, and a knowledge-based system has been developed to enable designers to carry out the stampability evaluation automatically. The effectiveness of the intelligent feature-based DFS system for improving the stampability of part designs lies in the integration of design evaluation and cost estimation into a single knowledge-based system. Such integration should enable consistency in cost estimation and design evaluation. The application of the system is illustrated with an example.
