Abstract

Fine-blanking is an effective and economical precision forming process that plays an important role in the manufacturing industry. Several factors, such as material, shape, and blankholder, can affect the quality of products. This paper reports some state-of-the-art research, which includes some changes in the material and shape of products, the evolution of blankholder, and the development of tools and presses. Meanwhile, some key facts about die roll, which is an important indicator when evaluating the quality of products, as well as digital technology, are introduced. Finally, an outlook of fine-blanking is provided with respect to the present situation, demonstrating its challenges and applications in the development of electric vehicles.
