Abstract: The main influence on the dimensional accuracy in incremental sheet metal forming results from the compliance of the involved machine structures and the springback effects of the workpiece. This holds especially for robot based sheet metal forming, as the stiffness of the robot’s kinematics compared to a conventional machine tool is low, resulting in a significant deviation of the planned tool path and therefore in a shape of insufficient quality. To predict these deviations, a coupled process structure model … Show more

“…As explained by the authors, the main drawback of this procedure is that the forming of a dummy part is required. The hypotheses used in the FEA of the process made by Meier et al [2009b] can explain the inaccuracies of the numerical model and finally the choice of this strategy. With these hypotheses the simulated forces through the forming of a straight groove present a maximum overestimation of 30% compared to the measured ones.…”

“…As numerical example the forming of a horizontal flute [3] was investigated. A horizontal flute of 100 mm length and around 5 mm depth was formed in a 220 × 220 × 0.8 mm clamped sheet metal.…”
