The use of advanced high strength steels in industrial
applications has been gradually increasing. In bending
operations, it is extremely important to obtain parts at accurate
dimensions. Depending on the properties of the material and
operation used, bending process results with springback. In this
study, the effects of punch radius, sheet material thickness, and
material type on springback in U-bending operations were
investigated. Springback values of the materials were determined
by analyzes using Deform software. DP600, DP1000 and JAC270
sheet materials were used for bending analyzes. In addition, the
effects of bending parameters on springback were identified
using the Taguchi method. Studies have been carried out based
on the Taguchi L27 vertical index. The effects of bending
parameters on springback were evaluated by using variance
analysis (ANOVA) and the main effect graph with the 95%
reliability. Finally, a regression analysis was performed to
estimate springback values and a model was created.
