This article provides an overview of the incremental sheet forming (ISF) process and discusses the process variations of ISF. These variations include single-point incremental forming, two-point incremental forming, and kinematic incremental sheet forming. The article discusses the machines and equipment used in the process and describes the process parameters, process mechanics, and process limits. It illustrates multistage forming strategies and summarizes difficulties that exist with regard to the finite-element process simulation of ISF process. The article also describes hybrid process variations, such as stretch forming and laser-assisted ISF.

Aluminum and its alloys are among the more formable materials of commonly fabricated metals. This article discusses the formability, bendability, and springback of aluminum and its alloys. It describes the forming limit diagrams that illustrate the biaxial combinations of strain that can occur without splitting. The article reviews various bending methods, such as draw, compression, ram and press, roll, and stretch or tension bending. It describes the process variations of incremental sheet forming (ISF), such as single-point incremental forming, two-point incremental forming, and kinematic incremental sheet forming. The article concludes with a discussion on spinning, warm forming, and superplastic forming.

Rapid prototyping (RP) techniques in the sheet-metal forming industry is developed to quickly test the form and fit of new sheet-metal products on a prototype basis as well as for production runs characterized by small lot sizes. This article provides an overview of some of the technologies used for RP and low-volume production of sheet-metal parts. It discusses low-cost tooling and flexible sheet-forming processes and reviews the various aspects of incremental sheet forming.
