Summary, etc. In the present work, finite element analysis is carried out for the minimization of springback in theV-bending process for high-strength brass sheet metal. Firstly, the uniaxial tensile test is conducted to determine the variousmaterial properties required for finite element analysis. The various test parameters considered in the V-Bending process aretemperature (573 K, 673 K and 773K), punch speeds (1 mm/min, 5 mm/min and 10 mm/min), holding time (30 s, 60 s and90 s) and sheet orientation concerning rolling direction RD (00), ND (450) and TD (900) for finite element analysis. Thebending under tension test is used to determine the coefficient of friction at different temperatures and lubricationconditions, and these values are implemented in finite element simulations of the V-bending process. Taguchi analysis iscarried out to determine springback of high-strength brass alloy by selecting four control factors (temperature, punch speed,holding time, and orientation). From the analysis of the signal-to-noise (S/N) ratio, it is reported that the temperature(46.93%) is the most significant parameter which influences the springback followed by holding time (26.29%), sheetorientation (24.07%) and punch speed (2.69%). The optimal set obtained for the minimum springback of brass alloy and theconformation test is performed at the optimum set conditions (773 K temperature, 1 mm/min punch speed, 90 s holdingtime, and 90° to the rolling direction of a sheet). With the optimal set of process parameters, Springback decreasedsignificantly to around 68.68%. Through the investigation of springback analysis, it is directly proportional to thetemperature and holding time and inversely proportional to the punch speed, but sheet orientation doesn’t follow any trends.
