Punching process is an operation that a scrap is separated from a metal sheet by a punch. Improper setting of punching conditions may lead to excessive of material deformation around edge region (burr), which may weakening the strength of produced part. Analysis of punching mechanics would be beneficial reducing defective part. One of effective analysing tool for this application is Finite Element (FE) method. The aim of this study is to develop reliable FE model for analysis of punching process. The FE model was developed based on 2D. FE result was validated with experimental testing result by comparing burr height. It was found that FE result is-1.79% difference compared to experimental result. Good agreement between FE and experimental result was obtained.
