Incremental sheet metal forming (ISF) is an innovative and flexible sheet metal forming technology for rapid manufacturing of complex parts. To further understand the ISF deformation mechanism, we investigates the process of ISF of aluminium and stainless steel cone both experimentally and numerically. The output of finite element simulation is given in terms of final geometry, the thickness distribution of the product, the strain history and distribution during the deformation as well as the reaction forces. Comparison between the simulation results and the experimental data are performed. In addition, the Springback effects arising in single point incremental sheet forming is studied in the use of a FE model based on shell elements to perform simulation of the process. The measurements of geometrical profile of a truncated cone and Springback of cut rings show that the FE model allows to predict accurate results for a set of well-defined process parameters.
