An analysis of single-pass conventional spinning process

Conventional metal spinning is a complex flexible manufacturing process with high efficiency for small and single series of parts. Spinning also has a possibility of producing parts that could not be deep drawn. In this paper, single-pass conventional spinning process, with straight line roller trace, has been studied. Spinning has been taken as a rotational forming process that is not set out to change the wall thickness. Both, the blank and the formed product have roughly the same thickness. Flat disk has been formed by a spinning operation into a cylindrical shape. The used material was St14 steel. Theoretical and numerical analysis of metal spinning process has been discussed to investigate stressed state as well as forming force components. Finite Element (FE) simulation model was developed with the MSC MARC software. By comparing the forming force components of the experimental samples with the corresponding numerical results good agreements have been observed with the maximum error less than 6%, while analytical error was more significant.
