Research on Ball Spinning Forming of Superalloy Inconel 718 Thin-Walled Tube
Ball spinning is an effective process to manufacture thin-walled tubular product of superalloy Inconel 718, which has been used widely in aerospace and other fields. In this literature, ball spinning process of superalloy thin-walled tube was investigated using software DEFORM. The build-up phenomenon and its influencing factors like principal axis speed, axial feed rate and wall thichness reduction were investigated using the finite element method (FEM). The experiment of ball spinning process was perfomed based on the proper technical parameters obtained by simulation. The simulated results agreed well with the experimental results.
