Hydrodynamic lubrication analysis for tube spinning process

This article aims to have a glimpse into the effect of the spinning tool parameters (focusing on its diameter, attack angle, nose radius, and feed) by applying the explicit code of the commercial finite element analysis software LS-DYNA. The preliminary results show that the greater the axial feed, the greater the loads generated in the axial, the tangential, and the radial directions. At the same time, the larger the axial feed, the more the elements are parallel to the axial direction from the inflection point to the tube opening. Furthermore, using a larger axial feed will also cause the flaring of the tube opening and make the flaring more obvious. In addition, using a larger axial feed will not only cause a greater material accumulation in front of the attack angle, but also a larger material accumulation at the tangential rear of the nose radius. Moreover, the greater the attack angle, the greater the axial load. There is no further significant effect of the corner radius of the spinning tool on the spinning load.
