The main goal is estimating useful setting of leveling machine to minimize curvature of particular material which is determined by measured geometrical data and given material characteristics as input information to the algorithm. The program is compiled with software MATLAB. Suggested algorithm which is fast is based on the Finite Element Method (FEM) and its fundamental equation. The curved bar passes through laterally offset rollers with cyclic elasto-plastic deformation resulting in convenient redistribution of residual stress which brings down curvature of long product. Solving of this problem is complicated due to high inherent nonlinearity, instability or sensitivity caused by cyclic plasticity of leveled material. The useful setting is found by iterative process applying Newton-Raphson method for solving nonlinear problems
