Incremental sheet forming is a flexible process that uses a hemispherical tool moved by a CNC machine to form a blank sheet. It is adopted in the production of prototypes, small series or customized parts since it is characterized by low costs and higher process times with respect to traditional forming technologies. One of its main lacks is represented by the low geometrical accuracy, therefore solutions for errors reduction or compensation are required to improve the process. In this paper, an iterative algorithm based on an artificial cognitive system is presented and validated on a not axisymmetric part adopting different tool paths and materials. The results show that the integration of the proposed algorithm with the ISF manufacturing system allows to improve its intelligence and to achieve a geometrical precision similar to the traditional forming processes.

Abstract
Incremental sheet forming is a flexible process that uses a hemispherical tool moved by a CNC machine to form a blank sheet. It is adopted in the production of prototypes, small series or customized parts since it is characterized by low costs and higher process times with respect to traditional forming technologies. One of its main lacks is represented by the low geometrical accuracy, therefore solutions for errors reduction or compensation are required to improve the process. In this paper, an iterative algorithm based on an artificial cognitive system is presented and validated on a not axisymmetric part adopting different tool paths and materials. The results show that the integration of the proposed algorithm with the ISF manufacturing system allows to improve its intelligence and to achieve a geometrical precision similar to the traditional forming processes.File | Dimensione del file | Formato | |
