Incremental Sheet Forming
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.
