Water jetting technology: an alternative in incremental sheet metal forming

This exploratory paper aims to introduce a high-speed Water Jet (WJ) as a tool for die-less Incremental Sheet Metal Forming (ISMF). First experiments indicate that in the case of Water Jet Incremental Sheet Metal Forming (WJISMF) the forming time, energy efficiency and forming accuracy are rather poor compared to ISMF with a rigid tool. However, the proposed technology brings higher process flexibility and better tools to workpiece interface conditions. For a better process characterization, the relative jet diameter is introduced, which is defined as the ratio between the WJ diameter and the blank thickness. Relevant process parameters are identified and technological windows are phenomenological defined, shoving that WJISMF can be applied as a complementary solution to ISMF with a rigid tool.
