A model for productivity improvement on machining of components for stamping dies

Abstract

The production of stamping dies requires the manufacture of numerous components, many of which have similar dimensions. However, because they are almost all different, this brings added problems in the acquisition of materials, and in their machining, the main process used in the manufacture of these components. Most SMEs do not have production systems properly organized to manage the machining of these components in the most cost-effective way. The purpose of this work is to provide a novel tool able to re-organize the machining operations in the production of dies for stamping operations, saving time and allowing an easy way to extend the autonomous machining time. This work follows an empirical approach resulting from the experience and attempts to optimize machining operations in the production of stamping dies. A flowchart was developed, acting as guidelines to select if the set of parts to be manufactured can integrate the approach designed. The approach is validated by two case studies presented in the paper.
