| Abstract Scope |
Beside the manufacturing of finished parts by Incremental Sheet Forming (ISF) final operations within the process chain can also be realized with this technology. The technological capabilities of performing incremental (hole-)flanging operations for sheet metal parts has been investigated in research context. The current topic focusses on the transfer of the incremental forming technology to manufacture tubular parts. An incremental collaring process was developed where all motions are executed by the forming tool. Due to the fixed position of the workpiece, tubes as well as pipes can be branched. Stainless steel tubes made of 1.4404 (316L) with an outer diameter of 54 mm and a wall thickness of 1.5 mm were used for numerical simulation with FE-software Abaqus/Explicit and comparative forming experiments. The influence of varying process parameters (e. g. pre-hole geometry, step size) on the properties of the tube collar (e. g. geometric accuracy, wall thickness) was investigated. |
