Design for Stamping: a Group Technology-based Approach

Abstract

The design of parts for metal stamping is often accomplished following a rules-of-thumb-based design process. The approach descnbed here, as part of a broader design for manufacturability (DFM) strategy, is based upon detailed models in contrast to rules of thumb and is developed through extensive interactions with toolmakers and stampers. The design for stamping (DFS) system includes consideration of costs due to rooling, costs due to processing, and costs due to material where these costs are functions of the part design, thus enabling qualitative and quantitative assessments at a preliminary concept sketch as well as further developed design stages.
