Development of Initial Blank Geometry in Sheet Metal Forming Processes Using Finite Element Analysis

Sheet metal parts have a wide usage are due to their weight/strength ratio. Process design is a critical step for sheet metal forming processes. Determining initial blank geometry is crucial for process design. Material wastage can be reduced by obtaining the optimum initial blank geometry. In this study, a methodology, for developing initial blank geometry for square drawing process using aluminum 5754 alloy considering process parameters and product geometry based on finite element analysis, is presented. A crucial material acquisition and a safe geometry regards to formability properties is obtained with the new blank geometry
