A deriving method of bending roll position in forming of glasses frame is proposed. The proposed method requires not the computational simulations but only some simple bending tests. To obtain a relationship between bending roll position and bent curvature which depends on material and cross-sectional shape of bent wire, simplified bending experiments in steady bending condition for getting constant curvature are carried out. The experimentally obtained relationship is used in the formulation of deriving the bending roll position for forming glasses frame having curvature distribution. To validate the proposed method, three different shapes are formed by the proposed and conventional methods. The difference between the designed and formed shapes is evaluated by a sum of absolute of shape deviation, and the value by the proposed method is smaller up to about 50 % than that by the conventional method.
