Incremental sheet forming (ISF) significantly exempts use of expensive dies and reduces tooling cost for manufacturing complex parts in the field of sheet metal forming which makes it suitable for manufacturing prototypes and low volume production as compared to other traditional sheet metal forming processes. ISF also finds suitability for producing components of old machinery, which are otherwise very difficult to form due to the unavailability of forming dies. Moreover, the incremental nature of the process and local deformation of the sheet ensures higher formability and lower required forming force. To take advantages of lower required forming force, it is important to minimize and estimate forming force through the manipulation of the parameters for the safe utilization of hardware. In this review article, a literature survey was carried out quantitatively to study different aspects of ISF, especially to show different process parameters and techniques that affect the forming forces significantly. The current state of the art of the ISF process has been discussed with detailed analysis of process capabilities and limitations in terms of forming forces. Influences of different process parameters and forming techniques have also been studied on forming forces. Some parameters have shown their significance to control the forming force in order to preserve forming machinery. A lack of focus was found on effects of some important forming process parameters and methods, which could have been crucial for safe utilization of forming hardware. A number of guidelines have been recommended for future research work. Appropriate guidelines have also been suggested regarding the relationship between process parameters and forming forces developed during the process in order to ensure the applicability of the ISF process on the industrial scale.
