Study the optimization parameters for spring back phenomena in U-die bending

Abstract EN

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 o 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.
