Review on Investigation and Optimization of Blanking Process using FEM and DOE technique to Analyze the Influence of Process Parameters on the Burr Height

With the current state of the global sheet metal industry, the market demand for mass production of sheet metal parts at cheap price and high quality is a big challenge. The Sheet metal blanking is a commonly used metal fabrication process in automobile, aviation, electrical & electronics, Heavy machineries and other industrial equipment. Burrs are the unwanted piece of material and ragged-edge raised on the surface of the blank after blanking process. The formation of burr on piece of metal decreases its quality, precision and usability of the metallic blank. So, it has to be detached by further processing like machining or deburring that also increases the Cost per part in production. Picking appropriate set of process factors can decrease the extent of Burr. In this paper, review on finite element simulations of the blanking process using the Ansys/Explicit Dynamics software package with various Set of process parameters, Also the Design of experiments (DOE) methodology applied by author & effects of the process parameters on the burr formation and equivalent stress is studied
