Influence of Process Parameters on Limiting Drawing Ratio of IS513 CR3 Grade Steel Sheet during Warm Deep Drawing

Abstract

In this work the significance of important parameters such as Blank temperature, Blank hold force on limiting drawing ratio (LDR) of IS513 CR3 steel sheets during warm deep drawing was determined. Influence of these parameters was analyzed at three different forming speeds. Experimental results proved that the blank temperature has a higher influence on LDR compared with other parameters especially at low forming speed.
