Özet: Sheet materials, which are commonly used in sectors such as automotive and whitewares, are usually formed by applying bending operations. The most important problem encountered in bending processes is springback. Springback problem arising from elastic behavior of the material complicates the assembly of manufactured part due to dimensional differences and causes financial loss. For this reason, it is required to properly estimate the springback behavior to provide the dimensional integrity and cost savings of the shaped parts as a result of the bending operations. In this study, the springback behavior of DC series sheet metals forming by V bending was experimentally investigated the different process parameter of material quality, thickness, rolling direction and die angle. The sheet metals have the quality of DC01, DC04 and DC05 and the thickness of 1, 1.5 and 2 mm. The V-bending dies have 60, 90 and 120o angles. From the experimental studies, it is seen that the behavior of springback changes depending on the die and the process parameters.
