“…They found that for multi-pass conventional spinning, the reasonable roller trace design method can lead to lower thickness variation of spun parts. Similar results can be found in the following works [5][6][7][8]. To reduce the wall thickness variation, Xiao et al [9] claimed that the circumferential distribution of the wall thickness can be varied by changing the geometry of the roller pass circumferentially in synchronous multi-pass spinning.…”

Power spinning is a single point high pressure forming process which is usually studied with ideal regular billet. However, in some cases, the billet adopted in this process is from conventional spinning process with non-uniform wall thickness and springback. Therefore, the forming accuracy is low because this unpredictable spun billet. In this paper, cone, step and arc rollers are compared and the length change of deformation zone is calculated to further understand the forming mechanism of different roller shapes. Multi-step process simulation considering conventional spinning and power spinning is established. The influence of roller parameters such as roller nose radius, straightening zone in step roller and bite angle on the maximum roller force are discussed. In addition, the continuous factors such as installation angle and discrete factor roller shape are studied based on the response surface method (RSM) with categoric factors. The results show that roller shape have a big influence on the workpiece forming quality in power spinning process.Step roller is more suitable for use in this work. The roller nose radius and installation angle have great impacts on the maximum roller force.

“…All measured heights achieve the higher values, up to the 38.404 mm. Hence, the application of concave tool path has a negative effect on the height of the spun part from the technological point of view, since in the previous research [32] was observed that concave tpp causes the most massive thickness reduction in the wall zone of the spun cups. This conclusion is also confirmed by research of Šugár [33].…”

This research paper deals with the influence analysis of the conventional metal spinning parameters (tool path profile tpp, tool feed f and mandrel rotational speed n) on the wall heights and the surface roughness Ra of the cylindrical-shaped spun parts measured in various directions with respect to the material rolling direction. Experimental research was carried out according to the 3-level full factorial design of experiment (DoE). Experimental study was also statistically analyzed by the ANOVA method. It was observed that tool path profile is a process parameter which has the most significant impact on the spun cup height and the surface finish, as well.

This study clarified the evolution of texture in the thickness direction of the cylindrical cup which was spun from a rolled aluminum sheet in 13 passes, using electron backscatter diffraction pattern analysis. The study also obtained the relationship between the strain and layer structure, characterized by the textures. The spun workpiece had three layers in the thickness direction. The layer structure was composed of four types of textures: the Cu texture, “texture-I”, which rotated 20° around <111> from the Cu texture; “texture-II”, which rotated 5° around its <110> from the Cu texture; and “texture-III”, which rotated 10° around its <001> from texture-I. When a blank disk had the sandwich-type layer structure Cu-I-Cu in its thickness direction, the structure changed to the Cu-II-II and Cu-III-III layer structures for the negative and positive thickness directional strains, respectively. A complex-type structure was found in the transition from Cu-I-Cu to Cu-II-II and Cu-III-III.
