Effect of Different Anisotropic 3D Yield Functions on a Roller Hemming Simulation

Hemming is a materials processing technology widely used in major sectors such as automotive and aerospace industries. As a mechanical joining process, hemming is applied to sheet metal components to build structural assemblies. In conventional hemming methods, dies and presses are used by designing product-specific equipment. In recent years, robot technologies have been integrated into this specific process to benefit from the advantages of flexible manufacturing systems. In this paper, a state-of-the-art review of the hemming process is presented based on a literature review. Since there is no background of collected works and systematic reviews, this work summarizes all the details and key points about hemming. This review fulfils the need for compiled knowledge at the right time because of two main reasons. First, there is no review currently on this issue to enlighten both industry and academia. Second, hemming technologies have been enhanced by the leading industrial companies without any contributions of written sources to the literature. In the present work, the evolution of hemming technology is given from past to present. Deformation mechanisms in different hemming methods are presented. Effects of process parameters are discussed in terms of product quality, mechanics of materials and manufacturing aspects. Last, recent developments in hemming technologies are given. As an unrivaled materials processing technology, hemming comes to the forefront amongst the other sheet metal joining processes. Despite alternative joining methods, this simple technique will maintain its importance in future sheet metal applications.
