Prescriptive Analytics - A Smart Manufacturing System for First-Time-Right Printing in Wire Arc Additive Manufacturing using a Digital Twin

Year: 2023

Type: article

Abstract: First-time-right printing is needed for extensive industrialization of Wire Arc Additive Manufacturing. However, due to process instabilities defects can occur even if suitable process parameter were chosen, resulting in production scrap due to an insufficient part quality. In this paper, we propose a smart manufacturing system which enables the compensation of previously created defects by means of a Digital Twin. We predict the future position of the welding torch, analyze its spatial context and adapt the process parameter if needed accordingly to compensate defects. Using this approach, a fault-tolerant manufacturing process is enabled, resulting in a first-time-right process.
