To realize the accuracy forming of diverse bent tubular components, the influences of geometrical parameters including the bending angle θ , the relative bending radius R/D , the outside diameter of tube D and the wall thickness of tube t on springback behaviors of high strength TA18 tube in numerical control (NC) bending are explored by finite element (FE) numerical simulation method. The results show that with increasing the θ or the R/D , the springback angle linearly increases, which can be described as a linear equation. With increasing the t , the springback angle first reduces and then increases, while the springback angle fluctuates mildly with increasing the D. Under the same D/t , the springback angle declines with increasing the D and t proportionally.
