In this paper, the applications of a mesh-free smoothed particle hydrodynamics methodology for simulating and analysing the 3D slitting process is presented. The developed model is used to analyse the residual stresses and deformation in grain-oriented electrical steels during and after the process under different conditions. The experimental research included both assessing the quality of the cut edge of the material and an analysis of its selected magnetic properties. Obtained results are used in multiparameter optimization process with delivered scripts in Matlab program. A set of acceptable solutions is developed on the plane of controllable variables (of technological parameters) on account of accepted criteria (operational indicators) and limitations. Using obtained relationships, functions, and results, it is possible to control cutting process and obtain high cut surface quality and minimum deterioration of magnetic properties.
