in the first stage of this study, the process parameters that affect the springback which occurs after DP600 sheet metal is bent with V die were investigated experimentally. For the second stage of the study, the results from the first stage were transferred to a fuzzy logic system and the springback was estimated according to the experiment parameters that were not determined with the fuzzy logic method. Die angle, holding time and punch radius were determined as the experiment parameters. It was observed that a 15 degree increase in die’s angle raised the springback by average 0.61 degree, a 2 mm increase in punch’s radius raised the springback by average 0.13 degree, and a 10 second increase in holding time decreased the springback by average 0.12 degree. A 98.5% similarity was found when the results from the actual experiment and the estimations made with the fuzzy logic method were compared. It is determined that the fuzzy logic method can be used successfully for springback estimations in V bending operations.
