Rotary Draw Bending (RDB) is a common process in the tube bending industry but the problem of springback often occurs. When the clamp die part is released after the bending process, the bent tube will spring back as a result of the material deforming. Several studies have attempted to determine the factors of springback but there is no convincing empirical evidence to establish a relationship between the input and output factors of the tube bending process variables in springback problem. In this research, the factors affecting the springback angle by the Taguchi method in bending seamless tubes ASTM A-210 Gr. A1, outside diameter 44.45 mm, were established. The Taguchi method is used for medium carbon seamless tubes for steam boilers. The four factors that were considered included wall thickness, bending radius, dwell time and bending angle. The results showed that all factors have a significant influence on the springback angle in the tube bending process, and each factor affects the springback angle differently. The factors that affect the springback angle the most are Bending Radius with an impact of 43.01%, Bending Angle 25.16%, Wall Thickness 16.05%, and Dwell Time 15.78%. As well, the time-dependent springback principle has a significant effect on the springback response in tube bending.
