Increasing the part accuracy in dieless robot-based incremental sheet metal forming

Optimization of relative tool position in accumulative double sided incremental forming using finite element analysis and model bias correction

“…It was assumed that the compliance of the machine, which is present in physical experiments, could be used implicitly by the bias model to correct the results from Fig. 11 A process map when the desired angle is at 25°I the simplified simulation, but to obtain better experimental results the compliance of the machine must be used to correct deviations in the toolpath using an adjustment vector of the toolpath points [25,26].…”

Part precision improvement in incremental sheet forming of not axisymmetric parts using an artificial cognitive system

“…Errors are due to the sheet springback, stretching and bending [2,5] (Fig. 1a), local plasticization due to the punch contact [13], overspinning which results in unwanted bulging [5,14] or to a low machine stiffness [15]. Moreover, a curvature called "pillow effect" typically appears on flat surfaces [2,16].…”

Cranial Reconstruction Using Double Side Incremental Forming

“…A few strategies have been proposed: Cao et al [22] developed an accumulative forming approach, in which in-out toolpath strategy was employed. Meier et al proposed two DSIF forming strategies including DSIF with peripheral support and DSIF with local support [25]. Concerning the cranial plate to be generated as shown in Fig.…”
