FEM and Experimental Analysis of Industrial Forming Processes 2001-01-3218
This paper deals with implementing process simulation in the developing of the manufacturing process for automobile panels and body parts. Starting from FEM analysis of material behaviour, suggestions about punch and die design can be obtained bringing direct and indirect benefits to other routing steps, thus saving time and resources. In order to point out these relationship and enhance these benefits, some real cases are presented and analysed for which a comparison among simulated and experimental results is given, using both circle grid and thickness analysis of the deformed blank sheet. Suggestions for part design modifications have been obtained that lead to a net improvement in formability and quality.
