Streszczenie
The paper contains the results of experimental research on the AMS 5504 sheet spinning process. The research was carried out on a Leifeld SFC 800 V500 two-roller metal spinning machine with a vertical axis. Various shapes of rollers and different thicknesses of sheet metal were used.The relationships between the limiting spinning ratio, thin-wall ratio and the fillet radius of roller were determined, and the occurrence of negative phenomena during the spinning process, such as wrinkling or cracking, was taken into account. The conclusions contained in the work and the developed methodology allow for a practical assessment of the possibility of producing drawpiece with given parameters by spinning.
