CAM for On-line Control for Wire Arc Additive Manufacturing [PDF]

Computer-Aided Design and Applications, 2018
Wire Arc Additive Manufacturing (WAAM) has the possibility to build metallic structures in 3D space. WAAM system is based on welding process to deposit metallic material and on a robot that moves the welding torch to add material at a given position. For large skeleton structures, it was chosen to deposit material point by point.
