Accurate production is a critical aspect of the forming process in sheet metal businesses. Die clearance, Spring back, press load and tool radius are the most common reasons for uneven sheet metal parts during the bending process. The experimental investigation was conducted on a thick plate made of EN-3B Steel material with a thickness of 8 mm. A striking issue in sheet metal forming operation in both theory and engineering has been the bending of the steel material. Predicting this event and accounting for spring back throughout the process of bending remains a significant task today, the trials on this issue are limited. The three-point bending method is employed in this project work for the 8 mm thick plate bending process. ANN was used to analyse the spring back prediction model. It was observed that the matching loading stroke can potentially negate the deflection of the plate after spring back. Numerical simulations utilising the finite element method were run for punches with a radius of R8, R12 and R16 to explore the impact on spring back. Validation of the finite element model was done as per results.
