“…It shows that the distributions of strain, stress and thickness reduction of the non-axisymmetric tubular spun workpieces are non-axisymmetric and uneven. Awiszus and Härtel [7] and Härtel and Laue [8] investigate the spinning process for making noncircular parts by adopting modelling and experiment methods, and the process optimization has been proposed. Music and Allwood [9] put forward a flexible asymmetric spinning method by replacing the asymmetric mandrel with three rollers which can be controlled on a seven-axis machine.…”

Non-axisymmetric shell parts are widely used in the fields of aviation, aerospace and automobiles. Because of good flexibility, short production preparation period and low cost, die-less spinning has the advantages in processing those parts. However, the special work-hardening distribution being caused by its processing technology will affect the performance of these parts. Therefore, the work-hardening of nonaxisymmetric die-less spinning is studied through experiments and by using the finite element method (FEM). The law of "smaller half cone angle (HCA) with bigger work-hardening" is found by testing the surface hardness of the spun workpieces. Microstructure observation and theoretical analyses are adopted to reveal the law. The reason for that is that the roller causes greater plastic strain inhomogeneity in the smaller HCA-forming process. It is also found that the working condition with the largest HCA difference has the biggest work-hardening difference and the maximum hardness difference can be 15 %.

“…9. Asymmetric spinning [148] An opportunity to increase the economical relevance and flexibility of conventional metal spinning is the development of the process of "non-circular spinning" for producing rotationally non-symmetric components [16,17]. In principle, the production of rotationally non-symmetric, hollow components through spinning is possible with the application of force-controlled or motion-controlled roller tools shown in Fig.…”

Flexibility in metal forming is needed more than ever before due to rapidly changing customer demands. It paves the way for a better control of uncertainties in development and application of metal forming processes. Although flexibility has been pursued from various viewpoints in terms of machines, material, process, working environment and properties, etc., a thorough study of the concept was undertaken in order to with problems of manufacturing competiveness and tackle new challenges of manufacturing surroundings. Therefore, in this paper, flexibility in forming is reviewed from the viewpoints of process, material, manufacturing environment, new process combinations and machine-systemsoftware interactions.

“…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]. The spinning of "Tripode" and "Pagoda" shape workpiece were simulated by Awiszus and Härtel, then experiments were carried out to verify the simulation results [16]. Sekiguchi and Arai investigated the oblique shear spinning and tried to control the wall thickness distribution after spinning [17].…”

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.
