Incremental sheet forming
Incremental sheet forming (ISF) is a metal forming process that uses localized deformation from a tool to form a sheet of metal into a 3D shape through a series of small increments. ISF has potential advantages over other sheet metal forming processes as it does not require dies, allows for localized production and reworking, and uses lower forming forces. However, ISF is not widely used in industry due to challenges achieving optimal mechanical capabilities and accuracy without expensive tool path optimization or workpiece support, and limitations of current machinery and tooling designs. The document outlines ongoing research projects at IfM to address these challenges through areas like tool force prediction, sandwich panel forming, real-time process control, and flexible workpiece support to
