Abstract

Rotating draw twisting (RDB) is among the best-known techniques utilized for cylinder shaping. Twisting profiles are utilized in most mechanical fields, including car design, aeronautic design, plant building, fluid transport, heat exchangers and many other sectors. Ovalization affects the nature of cylinder bowing. It occurs in the cross segment of the cylinder in the wake of bowing when the cylinder has twisted without a mandrel, or with a change of mandrel structure. This paper examines the ovalization phenomenon in cylinder bowing with turning draw twisting procedure and utilizing distinctive material properties (types of material: 1.4301(2x40), 1.0036(2x40), 6060T7(2.5x40), 1.4301(4x40), 1.0038(4x40), 1.5415(7.1x51) and 1.7380(7.1x51)). The finite element method (FEM) and experimental tests are applied to compute the ovalization proportions. This investigation helps to distinguish the impact of the material properties.
