PURPOSE: A method of forming a curved surface is provided to minimize the bending radius of a bent material when molding the bent material. CONSTITUTION: A method of forming a curved surface comprises the steps of: placing a bent material on top of a pad installed between both side dies of a lower die(S200), press-fitting the side die to the bottom of the material(S210), and lowering a push plate of an upper die toward above the fixed die so that the upper part of the material is bent inward and compressed to have a small bending radius(S220,S230).
