| Abstract Scope |
An increasing product variety requires flexible manufacturing processes to enable an economical production. Single point incremental sheet metal forming is a flexible manufacturing process to produce complex shaped parts by the computerized numerically controlled movement of a hemispherical forming tool. In this paper, the basic forming mechanism and their relationship to the residual stresses and the hardening of the component in incremental sheet forming is identified. It is shown that three forming mechanisms exist: Bending, shearing and membrane stretching. These mechanisms are triggered by adjusting the ratio of tool step-down increment and tool radius. It is shown numerically and experimentally for linear and circular groove geometries that an increasing number of forming steps leads to a more pronounced shear domination and hardening effects of the material. The residual stress amplitudes decrease with an increasing number of step-down increments for the same final geometry. |
