| Abstract Scope |
Incremental sheet forming with active medium (IFAM) is a flexible manufacturing process that creates concave-convex sheet metal parts in one clamping without needing a counter tool or a die. In the first study of this new process [1], a conventional hemispherical tool has been used in interaction with pressurised air to manufacture concave-convex parts. Thereby the geometric accuracy was not satisfying, so that within the present study, a conical tool with dedicated angle is introduced to IFAM. The idea behind this tool concept is to restrict the inclined part wall to a target angle. At first, results from numerical investigation show an improvement of the accuracy when a conical tool is used to manufacture a truncated convex pyramid. Subsequently, experiments validate the numerical model and reveal an increased process reliability. Experimental investigations of truncated convex cones and concave-convex parts close the paper and underline the feasibility of the tool concept. |
