Abstract
The traditional process of mechanical cutting of electrotechnical steels, still have many advantages such as: high efficiency, no thermal deformation zone affected by hot ablation, the possibility of shaping products of any length of the cutting line. However, this process introduces a substantial plastic deformation to the sheet metal and causes premature edge fracture during the subsequent forming process. This causes the deterioration of the magnetic properties of material. The paper studies the effects of the technological parameters of shear- slitting process on residual stresses and strains, quality of sheared edge and selected magnetic properties based on ET 122-30 grain oriented electrical steel. For the study, a simulation model ofthe process using mesh-free method (SPH) is developed. To obtain knowledge of the influence of this parameters on quality of cut surface and magnetic properties of material, experimental research was done using vision-based measurement system, confocal and atomic force microscopes and system for testing soft magnetic materials. Finally, an example of graphical optimization is presented and set of acceptable solutions is developed on the plane of controllable variables. Using obtained relationships and results, it is possible to control cutting process to obtain high cut surface quality with minimum deterioration of magnetic properties.
