Abstract:

There are complex multi-layers accumulation and thermal effects in the wire arc hybrid additive-subtractive manufacturing process.The manufacturability is affected by many factors and difficult to be evaluated effectively.These factors make the process planning difficult to implement and inefficient.To address the aforementioned issues,a process planning method of wire arc hybrid additive-subtractive manufacturing considering weld bead sagging phenomenon is proposed.The relationship between forming quality and deposition height in different areas of wire arc additive manufacturing is studied,and the implicit models of target part and machining tools based on level set functions are constructed.A preliminary machining sequence construction method is proposed based on the matrix of the heights of the segmentation planes.The evaluation methods for tool interference and forming quality are established,and a process planning model based on particle swarm optimization algorithm is developed.The performance of the proposed method is verified through simulation and experiments.The results indicate that the proposed method can obtain an effective alternative scheme for the wire arc hybrid additive-subtractive manufacturing process,and is more efficient and adaptable for the wire arc additive manufacturing compared to traditional methods.
