Alternating Additive Manufacturing and Forming—An Innovative Manufacturing Approach

In this work, an innovative manufacturing approach that includes a fully linked and integrated system consisting of laser-based directed energy deposition (DED-LB/M) module forming press is presented. The alternating additive (AM) process based on combination DED-LB/M using laser power 600 W feed rate 400 mm/min subsequent process, in which the structure upset with hydraulic constant force 500 kN order to smooth surface influence accuracy components. For generation fundamental understanding, cuboid, basic shape was chosen as geometry for investigations. aim improve part properties by applying steps generate properties, are superior solely manufactured material. It shown structures can be adapted, top smoothed due operation. mean roughness value Rz decreases up 50% after hardness increased work hardening. Of special interest higher kept even though further step operation applied additively formed again. Finally, analysis new regarding its potential given.
