This paper presents a computer numerical control (CNC) deformation process, termed Bend-
Forming, for fabricating 3D wireframe structures. The process relies on the combination of …

With respect to wrinkling, wall thinning and cross section deformation, combined with
analytical description, the deformation behaviors of thin-walled tube NC bending with large …

Flexible-bending is a relatively novel bending method particularly suitable for the bending
process of profile and tube. Advantageous characteristics such as manufacturing profiles or …

A novel forming technology, designated as “radial hydro-forging bending (RHFB)”, was
introduced to alleviate the complication of springback in advanced high-strength steel …

The purpose of the present work is to study the correlation between the main geometrical
tube parameters of the rotary draw bending process and the resulting quality of the cross …

To achieve the precision bending deformation, the springback behaviors under various
forming conditions should be clarified preliminarily. Taking the thin-walled 6061-T4 Al-alloy …

In the over-bend straightening process of longitudinally submerged arc welding (LSAW)
pipes, the cross section tends to be distorted due to the axial curvature variation in the …

The tube numerical control (NC) bending process is a much complex physical process with
multifactors coupling interactive effects. The mandrel is the key to improve forming quality …
