Abstract
The manufacture of parts by metal forming is a widespread technique in sectors such as oil and gas and automotives. It is therefore important to make a research effort to know the correct set of parameters that allow the manufacture of correct parts. This paper presents a process analysis by means of the finite element model. The use case presented in this paper is that of a 3-m diameter pipe component with a thickness of 22 mm. In this type of application, poor selection of process conditions can result in parts that are out of tolerance, both in dimensions and shape. A 3D finite element model is made, and the symmetry of the tube section generated in 2D is analysed. As a novelty, an analysis of the process correction as a function of the symmetrical deformation of the material in this case in the form of a pipe is carried out. The results show a correct fitting of the model and give guidelines for manufacturing.

While the largest deviation between the formed pipes and the target shapes from the experiment and Finite Element Model (FEM) was about approximately 2 mm, the shape error is acceptable because it is in the allowable range
Summary
Metal forming processes for the manufacture of pipe-shaped parts require the generation of process models as an essential task of production engineering [1]. Robust process design and parameterization can be effectively evaluated with appropriate models [3], which helps feed the demand for tighter product tolerances [4]. The inclusion of these models and the virtualization of the work area and workpiece allow the digitization of manufacturing in the era of new smart factories [5].
