Two-Step Spin Forming of Thin-Walled Heads with Lateral Normal Flanged Holes
A thin-walled head with a lateral normal flanged hole is a key part of a propellant tank, and its low-cost and high-precision forming process is very challenging. In this paper, a two-step method is proposed to preform the head via marginal-restraint mandrel-free spinning and then to realize the fla...
