Abstract:Flow-forming is an unconventional incremental forming process that involves pressing and elongating a preform kept on a rotating mandrel with the aid of rollers. A 3D thermo-mechanical model is developed to simulate the reverse flow-forming of 15CDV6 Steel. This process can produce seamless cylindrical tubes in a single step with a high strength-to-weight ratio, reducing the need for additional manufacturing processes. Flow-forming also has an inherent advantage of producing tubes with almost uniform thickness… Show more
