Computer-aided design and simulation of strip layout for progressive die planning using Petri nets

Abstract

Planning of strip layout is one of the important activities of progressive die design in sheet metal industries. The optimum and economical die design mainly depends on the design of strip layout. Many methodologies are used to determine optimum strip layout, but there is no literature available for strip-layout simulation. Petri net is one of the most suitable methodologies for simulation of strip layout. In this article, two research contributions are described (1) to apply the visual Petri net to simulate the sequential workstations in the strip layout of part and (2) to integrate the parametric design of strip layout and simulation using Petri-net technique. To demonstrate the present research contribution, two case studies are also discussed.
