Forming Machine Qualification by Analysis of Manufactured Parts Geometry: Application to Aluminium Forming Process

Abstract

Today, manufacturing companies work in a concurrent engineering context. In this paper, we develop a methodology to validate the modelling of an aluminium forming process based on dimensional characterisation and finite element comparison. Generally, finite element modelling (FEM) is used to validate die design in parallel with an experimental process. In this work, we use FEM to design forming tools in a first step. In a second step, measurement in the three dimensions gives the sheet metal process machine tool errors, and it is necessary to integrate the reasons for these defects in the process of concurrent engineering in the field of metal forming. Finally, we conclude that multiscale models should be used to model the mechanical process.
