Abstract
Structural elements made from steel sheet metal have a great importance in today's industry. One of the biggest problems with the parts bended by using dies is the spring angle because it destines bent sheet metal out of manufacturing tolerances. So, it is vital to know a part’s spring angle properties in advance which are mainly dependent on the properties of the sheet metal and bending conditions. This study aims to investigate the effects of bending angle and punch radius on spring angle of sheet metal with rolling angle of 45o in V-die bending process. After being removed from the bending dies spring-back rates of the specimens were measured by using optical goniometer. At a constant load with respect to the bending angle and punch radius values, spring angle shaded off into spring-back angle or spring-go angle. In this study, it was observed that the spring angle is 0o when the appropriate value for punch radius or bending angle are taken depending on the other bending conditions.
