摘要

Incremental metal cold forming is a forming technique using simple shaped, flexible tools moving on a CNC-path. These processes are in general very difficult to control. The aim of this contribution is to provide a partitioned solution scheme that will help to accelerate the implicit, quasi-static Finite Element simulation of such processes.
