Spring-back in metal sheet bending was studied through extensive experiments and finite element method (FEM) analysis. The experimental work has been carried out to study the factors affecting the Spring back in sheet metal with different thickness by using different die profile radius . In this paper aluminum alloy 3105 sheets with 1 mm, 1.5mm, 2mm thickness and die with 50mm ,55mm radius. The finite element method (FEM) was used to predict stress-strain state and part geometry under load and the amount of compensation. Spring-back is dependent on yield stress, thickness of sheet metal and radius of die profile . Von misses stresses and directional deformation in X-axis at different operating conditions are drawn.
