Effect of Process Parameters on Incremental Sheet Forming: A Review

Incremental sheet forming is a process to produce sheet metal components that are well suitable for small batch prototypes. The process ISF is classified under sheet metal forming processes, more specifically in the asymmetric incremental deformation process. Some studies have been carried out to analyze the influence of different parameters (Speed feed, depth of cut, tool dia, tool path, Sheet thickness, etc,) in the process. Selection of appropriate process parameters such as tool path, feed, step depth, wall angle, tool diameter etc. with respect to selected sheet metal structure plays an important role for the reduction in processing time. Moreover, it provides a better understanding of the process, which will help for further improvement of ISF process, compare to other metal forming processes. Stretching in the plane normal to the tool movement direction and with shear in the plane parallel to the tool movement direction are the deformation mechanisms of Incremental sheet forming. Process parameters such as Tool dia and Depth of cut have a major influence over the surface roughness of the component, which has been discussed under.
