A computer process model provides a mathematically approximate description of the physical process of metal deformation. The most commonly used approximation method is the slab method.'' The slab method considers the stresses on a plane perpendicular to the direction of metal flow. When the forces on the slab are set at static equilibrium, the condition can be represented by a differential equation. By analytical or numerical integration of the differential equation, with appropriate boundary conditions, it is possible to calculate the forging forces. Application of the slab method to axisymmetric fie forging was divided into two stages: axisymmetric upsetting of the billet between dies; and radial flow to flash which starts after filling the die cavity. The modeling program was written in Fortran and integrated with computer graphics software FIGARO by MEGATEK.
