Özet:

 In this study, the bending behavior of AA5754 aluminum alloy was investigated using the three-point bending test. The three-point bending test is a method used to understand the elastic and plastic deformation behaviors of materials and to evaluate their hardness and strength properties. Experiments were conducted with different punch radii 3, 5, 7 mm, deformation speeds 2, 5, 10 mmmin, punch distances 30, 40, 50 mm, and rolling directions 0 and 90 to examine their effects on springback. In manufacturing engineering, springback is a critical issue and refers to the change in angle of the material when the punch force is removed during the forming of sheet metal materials. Springback measurements were performed using a universal protractor and image processing techniques. According to the experimental data obtained, increasing the punch distance led to an increase in springback. While increasing the punch radius along the rolling direction did not significantly affect springback, increasing the punch radius in the transverse direction resulted in greater springback. The effect of punch speed on springback was found to be limited. Minimum springback was observed in bending processes performed with a 3 mm punch radius, a deformation speed of 10 mmmin, and in the rolling direction. This study demonstrates the impact of various parameters on springback during the bending process.

 Bu çalışmada, AA5754 alüminyum alaşımının eğilme davranışı üç nokta eğme testi kullanılarak araştırılmıştır. Üç nokta eğme testi, malzemelerin elastik ve plastik deformasyon davranışlarını anlaşılması, sertlik ve mukavemet özelliklerini değerlendirilmesi amacıyla kullanılan bir test yöntemidir. Farklı zımba yarıçapları 3, 5, 7 mm, deformasyon hızları 2, 5, 10 mmdak, zımba mesafeleri 30, 40, 50 mm ve hadde yönleri 0 ve 90 kullanılarak yapılan deneylerde, bu parametrelerin geri esneme üzerindeki etkileri incelenmiştir. İmalat mühendisliğinde kritik bir konu olan geri esneme, sac metal malzemelerin şekillendirilmesi sırasında zımba kuvvetinin kaldırılmasıyla malzemede meydana gelen açı değişimidir. Geri esneme ölçümleri, evrensel açı ölçer ve görüntü işleme teknikleri kullanılarak yapılmıştır. Elde edilen deneysel verilere göre, zımba mesafesinin artırılması geri esnemenin artmasına neden olmuştur. Zımba yarıçapının haddeleme yönü boyunca artırılması geri esnemeyi önemli ölçüde etkilemezken, numunelerin haddeleme yönüne dik yönde zımba yarıçapının artırılması daha büyük geri esnemeye neden olmuştur. Zımba hızının geri esneme üzerindeki etkisi ise sınırlı düzeyde bulunmuştur. Minimum geri esneme, 3 mm zımba yarıçapı, 10 mmdak deformasyon hızı ve hadde yönünde yapılan eğme işlemlerinde gözlemlenmiştir. Bu çalışma eğme işlemindeki parametrelerin geri esneme üzerindeki etkisini göstermektedir.
