Experimental study of incremental forming of sheet metal products

In recent few years, new sheet metal forming technique, incremental forming, has been introduced. There are some different variants of incremental forming, two of which are compared in current study. There are some limitations Of using incremental forming processes. For example, it is very difficult to achieve vertical walls, and the thickness of final product depends directly on the wall angle. There are also some problems caused by residual stresses after forming. In this paper authors study the effect of residual stresses on the geometry of the final part. The experimental study has been performed using standard CNC milling machine and tools designed by the authors specially for the study of incremental forming processes.
