Robot-Assisted Cold and Warm Incremental Sheet Forming of Aluminum Alloy 6061: A Comparative Study

Incremental sheet forming (ISF) requires no or partial dies for metal fabrication and is widely used small batch production. In this process, necking either suppressed delayed due to the localized nature of tool–sheet contact; hence, more strains than conventional stamping deep drawing are obtained. present study, two variations ISF, namely cold ISF (CISF) warm (WISF), compared. First, FEA modeling carried out on ABAQUS reach forces involved in process. It found that WISF reduces forces. The temperature maintained at 180 °C. Following simulation analysis, tests out. force 55.77% less CISF. part fabricated by CISF slightly substantial WISF; however, depth can be achieved WISF. There a uniform thickness distribution case However, surface quality product inferior observed there reduced force, increased formability, better strain compared post-processing heat treatment polishing formed parts required restore their mechanical properties.
