- Abstract
- Ring rolling is a type of forging for manufacturing large-diameter rings. Products manufactured by ringrolling are useful in the aerospace industry because of their excellent mechanical properties and highdimensional accuracy. The major components of the ring rolling process are a mandrel and main roll thatshape the inside and outside of the ring, an axial roll that shapes the top and bottom of the ring, and a siderolls to position the ring. In this study, a simulation of ring rolling using finite element method (FEM) wasperformed. DEFORM, a commercial machining analysis program, was used. Based on the simulations, themandrel feed force required for machining and the drive torque of the main roll were predicted. It was alsopossible to identify the metal flow caused by machining.
