The aim of this paper is to develop a feasible forming condition under which the radial-axial ring rolling (RARR) process can be established successfully and then leads to diminished fishtail defects. The mathematical model for the RARR process is developed based on the constant volume condition of ring blanks and the constant growth velocity condition (CGVC) of a ring outer diameter. The feasible forming condition is determined by the reasonable rage of extreme growth velocities. For a verification of the feasible forming condition for RARR process, experiments are carried out.
