Abstract—The major problem associated with sheet metal forming is the springback, the geometric difference between the loaded condition and unloaded configuration and is affected by many factors such as orientation, force, gauge, and temperature. This work aims at predicting the influence of various operating parameters on springback in bending of Aluminum (Al) sheets. Taguchi’s Design of experiments is adapted to design the experiments and is conducted under different working conditions. The optimum condition that results in minimum springback is identified. This can be used to help design of tools in the metal forming industry. The purpose of this work is to present Taguchi’s approach for optimization of process parameters such as orientation, force, gauge, temperature on sample. The factors influencing springback effect of plane sheet of aluminum materials have been predicted quantitatively using the Taguchi Design of Experiment method. The bending process is chosen as an evaluation problem because of its larger springback effect.
