Abstract

This study is performed for investigating the effects of shearing characteristics in fine blanking, such as camber, burr-height and dimensional accuracy, etc by experiments. Conventional hydraulic press equipped with specially designed hydraulic unit is used for experiments. Cold rolled steel sheet(3.0mm) materials which got properties, 2212.39kgf of maximum, $29.490kgf/mm^2$ of stress and 41.33% of strain were used. it can be concluded that the center distance of vee indenter ring can be obtained 2.0mm in SPCC 3.0t.
