Toolpath generation strategy of wire arc additive manufacturing

Abstract

Wire-Arc Additive Manufacturing (WAAM) is a promising technology in the field of metal additive manufacturing, enabling the production of large-scale, complex metal components. A critical aspect of WAAM is the generation of efficient and accurate tool-paths, which directly influence the quality, structural integrity, and material properties of the fabricated parts. This paper presents a novel strategy for generating optimized tool-paths in WAAM, focusing on enhancing deposition efficiency while minimizing material waste and thermal distortions. The proposed approach integrates advanced computational algorithms with real-time process feedback to adaptively adjust the tool-paths based on in-situ conditions. Simulation and experimental results demonstrate the effectiveness of this strategy in improving build quality, reducing defects, and achieving consistent material deposition. The developed methodology offers a significant step forward in the automation and precision of WAAM, paving the way for its broader industrial adoption.
