  • Backward hole-flanging fechnology [!] using an incremental approach
    Petek, Aleš, 15.7.1980- ; Kuzman, Karl, 1941-2022
    The manufacturing of necks on the sheet metal parts using conventional hole-flanging process in small series production is sometimes too expensive or even impossible due to the complexity of the ... product. For these reasons, a modern manufacturing concept called the "backward incremental hole-flanging process" is proposed. It enables producing necks on the final products that can be very complex or even closed with minimal expense. Special attention is dedicated to researching technological particularities and limitations according to industrial requirements. Due to numerous input factors having various levels of influence, empirical modelling was selected with the aim of ensuring better prediction of results. It enables predicting the impact of each particular input parameter and their iterations on the selected output variables. Results show that forming tool diameter, and horiyontal and vertical step sizes have the greatest influence on the process. Moreover, the appropriate selection of process parameters results on a higher forming limit ratio and consequently, on larger necks achieved without cracks in comparison to the conventional hole-flanging process. The reason could be found in local incremental deformation of the sheet metal and a more suitable stress state.
