A Review on Incremental Sheet Metal Forming

Incremental sheet forming (ISF) has gained significant attention from researchers due to its better formability, die less process, cost-effectiveness, and adaptability for low-volume production and prototyping. Unlike conventional forming methods, ISF offers greater flexibility and does not require costly dies. This paper provides an extensive review of the developments in incremental forming, highlighting key progressions, current challenges, and the influence of various process parameters like wall angle, step depth, spindle speed on sheet forming process. The study aims to aid engineers and industry professionals in understanding the capabilities and limitations of ISF, thereby promoting its application in commercial manufacturing.
