Additive-subtractive hybrid manufacturing has realized significant development in recent years. Utilizing such hybrid manufacturing process chains, complex-shaped part geometries can be manufactured near net shape in a resource- and energy-efficient manner. However, key aspects for a successful application of these process chains remain the systematic selection of additive and subtractive part features, integrated CAD/CAM toolpath planning functionality as well as the accurate identification of the in-process workpiece geometry. This paper investigates the impact of exploiting hybrid manufacturing over traditional approaches on metrics such as cycle time, raw material usage, and energy demand to further drive sustainability aspects in the manufacturing environment. An experimental case study has been performed utilizing a hybrid manufacturing cell at the Institute of Production Engineering and Photonic Technologies at TU Wien consisting of a 6-axis wire-arc additive manufacturing (WAAM) robot with 2-axis part manipulator, a 3D-laser-scanner, and a 5-axis machining center.
