Numerical model design for accuracy prediction of parts made by hybrid incremental sheet forming

Hybrid manufacturing is a promising approach which helps to efficiently improve the performance of conventional manufacturing processes, just contemporary considering different technologies. The suitable combination of Incremental Sheet Forming (ISF) with subtractive or additive processes has been already demonstrated in the past as alternative approach to compensate excessive thinning or low accuracy of the produced parts. Focusing on the last solution, based on the coupled use of ISF and Additive Manufacturing (AM), a new challenge related to the design of a robust numerical model able to predict the behavior of the hybrid-material is still open. In this paper, this issue has been considered and an experimental-numerical validation is proposed.
