Importance of bending dies is very wide in sheet metal industry. Knowing that springback amount of bending material in bending dies is as important as the die itself, because the material leaving the die should be within the allowed tolerance limits. Therefore, in this study the subject of bending dies and springback in bending process has been researched. In order to find springback in bending, a "V" shaped die is designed and it has been aimed to find out how much can steel sheet metal materials resile in various angles and to bring forward springback graphics to add literature. There is little satisfying information in the literature regarding this issue. In order to reach a conclusion, 15 different dies have been prepared, more than 150 samples, each of which has been bent at least 10 times, have been bent and the obtained angles have been measured with profile meter. The acquired results have been statistically evaluated in a computer media and converted to graphics. (c) 2004 Elsevier Ltd. All rights reserved.
