Research Status and Development of Wire Arc Additive Manufacturing Path Planning

The reasonable planning of the path technology is of great significance to the smooth progress of the forming process of the arc additive manufacturing, the acquisition of higher precision parts and the improvement of the forming efficiency. In this paper, several common filling paths were summarized from the aspects of forming efficiency, forming accuracy and structure and performance. After analyzing and summarizing and combining with the actual situation, it was found that the combination of adaptive path spacing and composite filling path can better meet the requirements of production of arc additive manufacturing in real life. Finally, combined with the current research status, research difficulties and related national policies of arc additive manufacturing technology path planning, the future development trend of arc additive manufacturing technology is to realize the automation, intelligence and green manufacturing of complex components.
