Putting in place circular economy strategies is an urgent challenge to face. In this scenario, 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) component to recover both material and functions. In this paper, single point incremental forming (SPIF) process is used for reshaping sheet metal EoL components. The entire process chain was replicated including both deep drawing process (to imitate the end-of-life component) as well as SPIF operations (to obtain the reshaped components). The geometrical deviation as a consequence of SPIF operations was studied; two different SPIF directions (named inwards and outwards) were analyzed. A wide experimental campaign along with statistical analyses was developed to analyze effects of some geometrical parameters on the observed geometrical deviation. The results are promising as limited distortions were observed and sound components were obtained in all the analyzed process configurations. Despite that, some research is still needed to better standardize the reshaping process and bring it closer to an industrial applicability.

制定循环经济战略是一项迫在眉睫的挑战。在这种情况下，制造过程扮演着有效的材料再利用推动者的重要角色。科学家们必须努力寻找新的过程或重新考虑旧的过程以重新处理报废（EoL）组件，以恢复材料和功能。在本文中，单点增量成形（SPIF）工艺用于重塑钣金EoL组件。复制了整个过程链，包括深拉伸过程（以模拟寿命终止组件）以及SPIF操作（以获取重新成形的组件）。研究了由于SPIF操作而导致的几何偏差；分析了两个不同的SPIF方向（向内和向外）。开展了广泛的实验活动以及统计分析，以分析某些几何参数对观察到的几何偏差的影响。由于观察到有限的失真，并且在所有分析的过程配置中均获得了声音成分，因此结果令人鼓舞。尽管如此，仍需要进行一些研究以更好地标准化重塑过程并使之更接近于工业应用。
