The products manufactured by the Sheet metal process are widely used in automobile and aircraft industries due to their high strength and superior surface characteristics. In this study, to improve the formability of the lamp-can, forming process was conducted using the Lancing engineering method. Lancing process is a press operation in which the work-piece is sheared and cut with one strike of the die to be a single-line cut or split, without removing any metal. Finite element method (FEM) was used to predict and investigate the improvement of formability of a lam-can with lancing process. As a result, it is believed that the Lancing process used in lamp-can forming would be helpful in the development of high-quality forming products because it can make material flow run well.
