Abstract

Three-roll tube bending is one of the cheapest technological processes. Nevertheless, during deformation a lot of problems occur which alter the quality of the bending zone. An experimental work and a numerical simulation are used to analyse the influence of process parameters, such as tube thickness, material and
bending angle, on bendenability, assessed through the study of the principal defects in three-roll bending, such as ovalization, buckling, springback, wall thickness
variation. The results could be used for improving the three-roll tube bending process and get the possibility to find new ways to improve this bending process.
