Set-up of radial–axial ring-rolling process: Process worksheet and ring geometry expansion prediction

This papers aims to give an answer to the problem of set-up for a cylindrical ring rolling process, giving the possibility to determine stable kinematic conditions for the key variables of the process (such as mandrel feeding speed, main roll rotational speed, etc.) and also to estimate the dimension of the initial blank used to obtain the desired final ring, minimising scrap material.
