Abstract Scope |
Wire-based Directed Energy Deposition (W-DED) is an often-preferred method for fabrication and repair of large metallic mechanical components because of its high deposition rate and cost-effectiveness. Utilizing higher kinematics for deposition in robotic W-DED facilitates the creation of overhanging structures without the need for additional support structures. However, a recognized universal solution for toolpath planning in robotic W-DED is lacking in current literature. Therefore, this study introduces a novel framework for computer-aided process planning for multi-axis deposition in robotic W-DED, using established CAD/CAM systems originally designed for machining. The framework initiates with the creation of a virtual robotic cell within the CAD/CAM system. Subsequently, the CAD model is imported into the CAD/CAM environment, and slicing planes are generated. The contours derived during slicing are employed for the generation of multi-axis toolpaths. Finally, a generic algorithm for post-processing the generated robotic toolpath is presented. |
