“…Shimizu et al developed a synchronous spinning machine, in which the rotational motion and feeding of the mandrel as well as the feeding of the rollers were controlled by the electric pulses to maintain the synchronization among the movements, as shown in Fig. 39 [50]. The trajectory of the rollers was tracking controlled by software, which taking into account the effect of the deviation generated by step-by-step pulse control on spinning process;…”

Metal spinning technology has seen a rapid development in recent years. Novel spinning processes, such as non-axisymmetric spinning, non-circular cross-section spinning and tooth-shaped spinning, are being developed. This has challenged the limitation of traditional spinning technology being used for manufacturing axisymmetric, circular cross-section, and uniform wall-thickness parts. In this paper, the classification of the traditional spinning processes is proposed based on the material deformation characteristics, the relative position between roller and blank, mandrel spinning and mandrel-free spinning, and temperature of the blank during spinning. The advancement of recently developed novel spinning processes and corresponding tool design and equipment development are reviewed. The classification of the novel spinning processes is proposed based on the relative position between the rotating axes, the geometry of cross-section and the variation of wall-thickness of spun parts. The material deformation mechanism, processing failures and spun part defects of the aforementioned three groups of novel spinning processes are discussed by analyzing four representative spinning processes of industrial applications. Furthermore other novel spinning processes and their classification as reported in the literature are summarized.

A three-dimensional elastic-plastic FE(finite element) model of power spinning of thin-walled Ti 2 AlNb alloy shell was established based on the dynamic, explicit module of FE software. The key technologies, including contact boundary, mesh, were dealt with reasonably. The reliability of model was validated by theoretical evaluation. To find a optimal combination of processing parameters, an L 9 (3 4) orthogonal test was adopted. The results showed that the feed velocity of roller had the most significant influence on the fracture trend, and the mandrel velocity on the wrinkle trend. The optimal processing parameters combination was v 2 n 1 r 3 t 3. Based on this model, the distribution of strain of both sides of workpiece was obtained in order to research the reason of the fracture and wrinkle of workpiece. The strain of outer side was larger than that of inner side. The results conformed to the practical power spinning process.

“…In their researches, multi-pass spinning and ball-shape roller were adopted, and the investigation results indicated that increasing the size of the ball contributed greatly to the stable flow of the metal as well as the formability of the inner ribs, but too large a ball led to the poor surface finish of the spun part; multipass spinning can guarantee the formability of the inner ribs [12,13]. Shimizu obtained the elliptical coneshaped products through synchronous spinning, but in his research, a mandrel with accordant shape was required [14]. Music et al designed and manufactured a seven-axis machine and used it to form some axisymmetric parts by replacing the mandrel with three rollers [15].…”

“…But this method easily leads to fold defects experiencing complex manufacturing process and long preparation cycle. As a result, some scholars developed spinning method for the square section cone [14,19] in which a modified mandrel die is needed with the shape corresponding to the square section cone. This will also bring in long preparation cycle and not suit the frequent changes of the parameters in the product development phase.…”

In view of the importance of the surface quality in the application to the square section die-less spinning, the effects of several key parameters which include roller path, half-cone angle, and roller nose radius on the surface quality are investigated. Through the geometric model of residual height, the effect law of the roller path is obtained: the surface quality increases with the decrease of the axial distance of two adjacent slices. Then the finite element model of the square section die-less spinning is established, and the normal force and axial strain states in the deforming process are adopted to predict the relationship between the surface quality and the half-cone angle. Combined with the residual height model and finite element analysis, the roller nose radius' effect on the surface quality is also obtained. Enlargement of the two parameters can improve the surface quality. All the analysis results are verified by the surface waviness test of the specimens from the workpiece after spinning.
