摘要

Incremental forming technology is gaining increasing attention from various industrial sectors owing to its adaptability and potential for customization. Nonetheless, some challenges such as poor geometric precision are impeding the industrial widespread of this method. Hybridization, cooperation between mechanisms/processes/energies/approaches, has lately emerged as a powerful approach to elevate the manufacturing competence. To this end, hybridization idea has been implemented in the area of incremental forming to address the pertinent challenges, and conducive outcomes have been achieved. The present article reviews advancements made in hybrid incremental forming. The article begins with a comparative analysis of contemporary and traditional incremental forming processes from multiple viewpoints. Subsequently, recent developments in energy-assisted incremental forming processes, categorized into cryogenic temperature-assisted, thermal-assisted and special energy field-assisted techniques (which encompass ultrasonic, electric, and electromagnetic fields), are summarized. The mechanisms through which special energy fields interact with materials and their subsequent impact on the forming quality of workpieces are systematically examined. Additionally, the benefits and drawbacks of various assisted methods are analyzed. Furthermore, the current state of research regarding the hybridization of incremental forming with other forming processes is outlined, which offers novel avenues for enhancing productivity and the quality of workpiece deformation. Lastly, the prospective advancements in hybrid incremental forming technology are presented to support its application in large-scale industrial contexts.
