This paper provides the experimental protocol, of the process of a single point incremental sheet forming “SPIF”, allowing predicting the efforts of forming. To speak about parameters of a single point incremental sheet forming (SPIF), we should find the good parameter for judgement. A prediction of the forming force during the SPIF process is selected to ensure the safe use of the tooling and machinery, in particular when using a robot or a milling machine not designed for the process. During the incremental forming process, considerable forces can occur depending on the studied material, the thickness of the sheet, the tool steps. In this work, the influence of several parameters on the evolution of the axial forming force during the incremental forming of a truncated cone is studied. A set of experiments is carried out using steel and aluminium sheets. The results on the most influent process parameters can be used to optimize the process. The results obtained are compared with those found by finite element simulations.
Key words: Incremental sheet forming / efforts of forming / numerical simulation
