Numerical and Experimental Study of Springback in Machining Forming of Thin Structure

Spingback is one of the important factors in metal forming process. Study on springback shows that this phenomenon can have great impacts on shape and formation of the part. Therefore, to increase the accuracy and the quality of the produced part, the important factors have to be recognized. In this paper, machining forming for thin part which is a combination of machining and incremental forming is first introduced. Then numerical and experimental results are compared. The effects of forming parameters such as tool diameter, part angle, forming steps, and tool position on springback are presented. The results show that the step depth has a great affect on springback.
