The Experimental Investigation of Springback in Titanium Grade 1 Sheet Material and Prediction by Fuzzy Logic
Journal Title: Gazi Üniversitesi Fen Bilimleri Dergisi Part C: Tasarım ve Teknoloji - Year 2017, Vol 5, Issue 3
Abstract
In this study, the springback phenomenon of Titanium Grade 1 sheet metal which is observed after V bending operations in room temperature was investigated experimentally. Bending angle, punch radius and holding time are determined as experimental study parameters. Also, the springback angles were predicted by using fuzzy logic system for non-performed experiment parameters. It was observed that a 15 degree increase in die’s angle increased the springback by an average 0.62 degree, a 2 mm increase in punch’s radius increased the springback by an average 0.14 degree, and a 10 second increase in holding time decreased the springback by an average 0.12 degree. A 93.3 % similarity was found when the results from the actual experiment and the estimations made with the fuzzy logic method were compared. It is observed that the fuzzy logic method can be used successfully for springback estimations.
