Incremental sheet metal forming on CNC milling machine-tool

Incremental sheet metal forming is a promising process providing a short and inexpensive way of forming products having a relatively simple but interesting shape. The paper presents the process controlled by CNC milling machine-tool together with CAD/CAM Master Cam system and a smooth forming tool. With experimental testing and measurements the limits of forming without a full-size model were defined. By using a simple full-size model and the concept where the sheet metal can move vertically in the clamping device, better results and products were obtained.
