Optimization of AL6061‐T6 Tube End Forming Process Using Response Surface Method
Modelling and Simulation in Engineering, Volume 2021, Issue 1, 2021., 2021 Tube end closing is a metal forming process that replaces welding processes while closing tubes ends. It depends on deforming a rotating tube using a roller, and therefore, it is also called tube end spinning. The process involves many parameters like contact depth, roller inclination angle, roller diameter, mandrel curvature, and tube rotational speed.
