Simulation Study of Effect of Various Parameters and Thickness Distribution In Deep Drawing of AISI 304 Stainless Steel Using AFDEX Software

In sheet metal, drawing is a process of forming flat sheet metal into hollow shapes by means of a punch that causes the metal to flow into the die cavity. This project aims to study the effect of various parameters on the deep drawing process. The project also aims to study the effect of these parameters on the thickness distribution in the final drawn cup. The material used for this study is AISI 304 stainless steel. AISI 304 is a widely-used austenitic chromium-nickel stainless steel. It has excellent drawing properties and very good formability. Modeling of workpieces and dies is carried out in SolidEdge V19. Simulation is carried out in AFDEX simulation software. The actual FEM-based calculation is performed by the simulation engine or solver. Based on the input data, necessary formulations are initiated by the software, and the required calculations are performed sequentially. A total of 15 simulations were performed in the AFDEX simulation software. In this study, three different cases are studied and in each case 5 simulations were performed. Variable parameters are binder holding force, die corner radius, and punch velocity. Whereas, co-efficient of friction and initial temperature is kept constant. Results were tabulated and analyzed for minimum damage value. Graphs were plotted to analyze the overall thickness distribution of the final drawn component.
