Development and analysis for the large-scale tee-forming process

In this paper, a different manufacturing technology for large-scale tee-forming is proposed by using a tooling set which can be assembled in a vertical or horizontal hydraulic press. A simplified analysis model is also proposed to predict material flow and fracture during forming. The following sub-titles are included, namely: (a) computer-aided parametric tooling design module, (b) computer-aided engineering of tee-forming process, (c) design guides for preparing a tubular billet with an elliptical hole by considering stress concentration and wall thickness reduction. Finally, an industrial case study is discussed as a demonstration example, in which a coincidence between the finite element analysis and the proposed simplified model is obtained.
