The main objective of the research is to find the optimum parameters that reduce the springback by using the commercially [SPSS] program to analysis data and find the best parameters which given lowest springback in the U-die bending. A commercial aluminum alloy [AL-1050] sheet (0.9 mm) thickness that founded when punch speed increase the springback increase, when rolling direction angle is 90 Lower springback, and when increase the dwell time decrease the springback, and the value of parameters predicted from [SPSS] have lower springback and obtain a goal dimension for the products. And predict the springback value by especial equations which given correlation coefficient 95.4% between the observed value of the dependent variable and the predicted value.
