Abstract Welding has been used for the direct fabrication of metallic prototypes and prototype tools by several research institutes. Since welding alone is not able to deliver the accuracy and the surface quality needed for prototype tools, especially for injection molds, a combination with conventional machining is necessary. In this paper, welding and 5-axis milling are combined together for the direct fabrication of metallic parts. For welding, conventional C02 arc welding is used. Test parts with conformal cooling channels and undercuts demonstrate the technological potential of this process combination for rapid tooling applications. (Auth abstract) [References: 5]
