• This paper reports about fundamental relationship between tip thickness of crushed cutter and thickness of wedged sheet. By varying the tip thickness of trapezoidal center bevel cutter, the resistance of cutter indentation and the shared profile of aluminum sheet were investigated experimentally. For discussing the deformation mechanism of aluminum sheet in the necking stage, Hill's solution with slip line theory and finite element analysis with elasto-plastic model were applied to this wedge indentation. The derived results were as follows : the necked height of sheet material is varied with the tip thickness of cutter; the occurrence limit of necking deformation exists in terms of the sheet thickness; the line force at the deflection point is varied with the tip thickness of the cutter, but not with the sheet thickness; the residual sheet thickness beneath the cutter tip depends on the tip thickness of cutter.
