Abstract: This work aims to study the springback behaviour of electrogalvanised (EG) steel sheets during the air bending process. Experiments have been conducted to analyse the influence of various parameters such as coating thickness, orientation of the sheet, punch radius, die radius, die opening, punch velocity, and punch travel on springback behaviour. It is established that the springback increases with increasing coating thickness, punch radius, punch travel, die radius, die opening, and punch velocity. The 90° orientation exhibits higher springback than 0° orientation.

Key words: Springback, Electrogalvanised (EG) steel, Air bending
