Machining Accuracy of Stamp Out Machining for Metal Thin Sheets (first report)

Abstract

In general, the clearance of the die and punch has a profound effect on the properties of shearing work. So the optimum clearance for general shearing work has been proposed. However, the optimum clearance for metal thin sheets has not been made clear. So in this study, we have carried out experiments on stamp out machining, which is a kind of shearing work, for metal thin sheets with various clearance and measured the profiles of cross sections of the holes. Thus, we have made clear the relationship between the clearance and shearing work properties.
