Recent Developments and Future Challenges in Incremental Sheet Forming of Aluminium and Aluminium Alloy Sheets

Due to a favourable strength-to-density ratio, aluminium and its alloys are increasingly used in the automotive, aviation space industries for fabrication of skins other structural elements. This article explores opportunities limitations using Single- Two Point Incremental Sheet Forming techniques form sheets from alloys. (ISF) methods designed increase efficiency processing low- medium-batch production because (i) it does not require matrix (ii) forming time is much higher than conventional sheet metal forming. The tool rotating mandrel gradually sinks into sheet, thus leading an degree deformation material. provides overview published results research on influence parameters ISF process (feed rate, rotational speed, step size), path strategy, friction conditions temperature formability surface quality workpieces. study summarises latest development trends experimental on, computer simulation using, finite element method processes conducted cold at elevated temperature. Possible directions further also identified.
