Effect of Punch Parameters on Springback for Mild Carbon Steel in A V-Shape Bending Process

The springback is variably sensitive to materials and process parameters. Considering springback occurred in a formed part is significant for designing tools and dies. In this paper, experiments of a V-shape bending test were performed for investigating the springback effect. The punch parameters variation has been observed in ASTM A-36 mild carbon steel. Punch radius used and punch angle). The V-shape bending of mild steel was performed using Universal Testing Machine (UTM) at various punch radius (2, 4, and 6 mm) and punch angle (80°, 85°, and 90°) and at constant of die radius (10 mm) and die width (50 mm). The experimental result indicates that the punch radius has a most significant impact on springback behaviour of these sheet metal. This is verified through our experimental work using V-shape bend testing.
