Understanding formability and geometrical accuracy of SPIF process used as reshaping approach
Putting in place Circular Economy strategies is an urgent action to be undertaken. Manufacturing processes play a relevant role as efficient material reuse enabler. Scientists have to make an effort either to find new process or to rethink old process to reprocess End-of-life (EoL) components to recover both material and functions. In this paper, Single Point Incremental Forming (SPIF) process is used for reshaping sheet metal EoL components. Deep drawing process as well as uniaxial pre-straining (to imitate the End-of-Life component) followed by SPIF operations (to obtain the reshaped components) are set- up and implemented to form and reform aluminum sheet metal components. As the authors…
An energy efficiency analysis of single point incremental forming as an approach for sheet metal based component reuse
Producing materials causes about 25% of all anthropogenic CO2 emissions. Metals play a significant role, steel and aluminum account for 24% and 3% of worldwide material related emissions respectively. Fostering resources efficiency strategies in the field of sheet components could lead to a significant environmental impact reduction. Reshaping could be one of the most efficient strategy to foster material reuse and lower the environmental impact due to material production. Specifically, for aluminum recycling, the overall energy efficiency of conventional route is very low and, more importantly, permanent material losses occur during re-melting because of oxidation. The present paper aims a…
On the effectiveness of spif process to re-form end-of-life components as compared to conventional forming approach
Manufacturing processes have a significant impact on global energy consumptions. The recovery of materials and functions for the implementation of the Circular Economy principle needs to be focused on either, by utilizing new techniques or the rethinking of old processes to rework End-of-Life (EoL) components. Previous researches have shown Single Point Incremental Forming (SPIF) process as a good alternative for sheet metal EoL components reuse by their reshaping. In this article, the authors aim to study the effectiveness of the SPIF processes by comparing its reshaping performance with other, more conventional forming processes. An initial Deep Drawing (DD) process was performed to imita…
