“…The definition of the hypocycloid can be seen in Figure 2, where a moving circle is inscribed into a fixed circle, and the moving circle rolls along the fixed one without sliding; then, the trajectory of any point on the moving circle is a hypocycloid. If the radius of the fixed circle is R, the radius of the moving circle is r, and a point P is fixed on the moving circle, then the trajectory of point P can be determined by the hypocycloid equation [30][31][32]:…”

Several researchers have developed various spinning methods to produce non-circular hollow parts. In this paper, an approach that the rollers revolve around the roller principal axis was used to generate a concentric circular trajectory to the spinning trilateral workpiece. The spinning simulation was performed in ABAQUS 2016/Explicit software. The trajectory of the roller is derived, and the distributions of the equivalent von Mises stress, equivalent strain, wall thickness of the workpiece in typical section and spinning force are obtained. The simulation experiment proves the feasibility of using the proposed spinning method to produce workpieces with trilateral cross-section. The results demonstrated that after seven passes, in the area where the roller unloads the workpiece and the area where the roller starts the forward pass, local wrinkling may be generated; the most vulnerable area of the workpiece is also located at the area where the roller starts the forward pass, while the overall thinning rate of the workpiece is below 21%. Compared with other existent non-circular spinning methods, this novel method could process non-circular parts with a high rotational velocity, while ensuring the roller processing trajectory with high accuracy. The application of this method will improve the efficiency of the process by more than 200% in theory, while ensuring workpiece quality

As a plastic forming process developed based on rotary wheel spinning technology, the rotary ring spinning process has the excellent characteristics of high forming accuracy and high material utilization rate, and has been gradually applied to the manufacture of bimetallic composite pipes. In this paper, the forming law of a bimetallic tube in the process of rotary ring spinning was analyzed by numerical simulation and experimentation. The results show that the deformation coordination of the basic and cover tubes increased with the increasing press amount, and the feed ratio had less of an effect on the thickness variation. In addition, the three-way strain of the basic and cover tubes and the degree of influence of the process parameters on the equivalent strain of the tubes were also studied. The results show that the radial strain on both tubes was the largest, followed by the axial strain, and the tangential strain was the smallest; the press amount had the largest effect on the equivalent strain of the tubes, followed by the angle of attack and the feed ratio. These results provide some guidance for the manufacture of high-performance bimetallic composite tubes by rotary ring spinning.
