Abstract

The V-grooving process is a pivotal technique in the realm of sheet metal forming, specifically designed to enhance the precision of V-bending operations. V-bending, a prevalent method for creating sharp folds in metal parts, often meets the issue of springback. This phenomenon, where elastic materials strive to return to their original form post-deformation, poses a significant challenge to the accuracy of metal forming. The study in question delves into the impact of V-groove depth on mitigating springback during the V-bending of SUS 304 stainless steel, a material known for its widespread use in the industry. Employing finite element analysis through the Abaqus Learning Edition 2023 software, the research simulates the V-bending process complemented by V-grooving to find the optimal groove depth that minimizes springback without leading to over-deformation of the metal. The findings suggest that a specific depth of V-grooves can significantly restrain the metal's tendency for elastic recovery post-bending, thereby enhancing the dimensional quality of the final product. This depth acts as a constraint, ensuring the metal keeps the desired angle after bending. While deeper grooves have been associated with reduced springback, they also carry the risk of causing excessive deformation, which can be just as detrimental to the part's integrity. The study identifies an optimal groove depth that strikes a balance, effectively minimizing springback across various bending heights. However, it acknowledges that the ideal depth may vary based on different applications and requirements. These insights are invaluable for industries that rely heavily on sheet metal forming, offering a pathway to improved dimensional control in V-bending processes. By optimizing the V-grooving technique, manufacturers can achieve greater accuracy in their metal parts, which is crucial for the functionality and aesthetic of the final products. The study's conclusions serve as a guide for future applications, potentially leading to advancements in manufacturing practices and the quality of metal-formed components.
