    (Cranfield University Press, 2013-09-19) Xia, Qinxiang; Qu, Juxin; Lai, Zhouyi; Xiu-quan, Cheng
    Processing parameters have great influence on forming quality of non-circular spinning. Finite element simulation model of non-circular spinning for the three straight-edge round-corner cross-section (TSRC) hollow-part was established. Variation rules of thickness and springback of TSRC spun workpiece under different processing parameters were obtained by means of orthogonal test as well as the software MSC.MARC. The results show that the influences of the relative clearance ΔC and the feed ratio of roller fz on the maximum wall thickness thinning ratio δt are obvious, and the influences of n and Dr are slight; the influences of the nose radius of roller rρ on the springback angle Δα is the most obvious, and the influences of ΔC and Dr are slight.
