Abstract

Abstract: Hole-flanging is a manufacturing process which is used to form flanges around holes by using sheet metal. A brief and concise review of the contributions made by the previous researchers in the area of hole-flanging process has been presented. Steel sheet material and aluminum alloys are used by researchers for hole flange forming. FEM modelling of hole-flanging is carried out by employing axisymmetric conditions. Meshing of the work piece is done by using axisymmetric quadrilateral elements. Experimental set-up and tools utilized in formation of hole flanges are presented and discussed. Results are presented in terms of variation of distribution of thickness along flange wall through conventional hole-flanging and incremental forming technique. Incremental forming techniques with different forming strategies is found to be more accurate, less complicated and better means of hole flanging in comparison to conventional forming techniques.
