Abstract
Incremental forming of sheet metal is a new sheet forming process. He has shown a variety of applications ranging from the automotive field to the biomedical field. However, sheet metal parts cannot be made in a one-step incremental forming process because the maximum profile angle of the wall that can be formed is limited for a given sheet material and for a given thickness. This limitation can be overcome with the multi-step incremental forming process (MSIF). In the framework of this study, it is proposed to analyze by experimental techniques the thickness and the profile of a truncated cone obtained by several steps forming an incremental MSIF. The study has been carried by forming a conical cup with 85° wall angle in four stages. Experimental tests were performed for specific conditions such as forming strategy, tool path, increment and cutting parameters. ABAQUS numerical simulations were performed to validate the experimental results at the end of each incremental forming step. The numerical and experimental results of the profile sheet metal are the subject of a comparative study between the theoretical, simulated and experimental models.
