The project focuses on studying the technological process of progressive bending using rollers and its impact on the resulting structure and mechanical properties of extracts produced by the single-point incremental forming (SPIF) method. The essence of the project is to analyze how various process parameters—in particular, the contact force of the rollers, their geometry, mutual position, feed rate, and number of passes—affect the deformation of the material during forming. Attention is also paid to how gradual bending by rollers modifies the stress state and distribution of plastic deformation in the formed semi-finished product and how these changes are reflected in the microstructure of the material, for example in grain size, texture, or degree of hardening. The solution also includes an evaluation of the mechanical properties of the extracts, such as strength, hardness, ductility, and residual stress, and their dependence on the selected process conditions. The results of the project should contribute to a deeper understanding of the physical nature of the combination of progressive bending and single-point incremental forming and enable the optimization of technological parameters in order to achieve higher quality extracts, better dimensional accuracy, and more favorable useful properties of the resulting parts.
