“…Upon forming spring-back will present always and cannot be eliminated but can be minimized by reducing elastic recovery of sheet metal with the help of suitable die design, and optimal setting of process parameters (Bakhshi-Jooybari et al 2009). To produce the parts with quality and economy, it is very important to take the spring-back into account and understand the bending mechanics to evaluate the spring-back and bending forces accurately (Gautam et al 2016). Deviation of shape and size upon forming the components causes rejection and hence it becomes essential to understand the spring-back phenomenon of the sheet metal components .…”

In recent decades the high demands of Dual-Phase (DP) brass find wide applications in electrical, electronic and other appliance industries. Therefore, study of material characterisation and springback behaviour are essential in forming of sheet metal components. In the present work, an isothermal uniaxial tensile test was performed to evaluate the accurate mechanical properties, which are essential pre-requisite for optimization of process parameters to decrease and minimize spring-back for any sheet-metal-forming operations. The V-bending test was conducted at specified test parameters temperature (773 K, 873 K, and 973 K), punch velocity (1 mm/min, 5 mm/min, and 10 mm/min), holding-time (30 s, 60 s, and 90 s) and orientation (0 0 , 45 0 , and 90 0 ) concerning rolling direction. Taguchi approach was utilized to optimize the test parameters such as temperature, punch velocity, holding-time, and orientation. The optimal set of parameters obtained were Temperature (973 K), Punch Velocity (1 mm/min), Holding-Time (90 sec) & orientation (90°) and using these optimal set of parameters a confirmation test has been conducted and it was reported that the spring-back was decreased significantly in V-bending process for dual phase (DP) brass sheet. The main objective of the study is to investigate the springback behaviour in V-bending process on brass sheets to understand the formability and to optimise the processes parameter to minimize the springback effect using Taguchi Technique to meet the needs of the sheet metal forming processes.

“…A numerical analysis of the bending process is yet another approach. The authors of [5] performed an FEM simulation of various thickness steel bending processes. It was confirmed that the value of the springback coefficient depends on the sheet thickness but it was demonstrated that after exceeding a certain critical value, further increase of sheet thickness again starts to have a negative effect.…”
