Study Of Springback And Bend Force In V-Bending Process of Perforated Steel Sheets

N. Ramu

Bending is an important manufacturing process in sheet metal industry. Springback is a crucial issue in the sheet metal bending and it affects the precision of the product. Bend force is the force required to bend the sheet metal. The work aims to study the influence of factors such as number of holes, hole size, distance between holes and sheet thickness on springback and bend force in v-bending of perforated sheets. The study is based on Taguchi’s design of experiments and the results show that the hole parameters and the thickness have a significant effect on springback and bend force.
