Sheet metal forming is a common process to produce various sheet metal based products like cylindrical cups, square cups etc. It has various types of defects which can reduce product quality, but wrinkling is the most critical defect in sheet metal products. Flange wrinkling is very common problem in sheet metal form based products and this is due to undesirable deformation of sheet, thickness and compressive stresses. When drawing process starts and increase draw depth, after certain height the flange region plastically buckles into a number of waves and the process fails down. It was found that small scale industries working in this field have less technical knowledge for forming defects.
