Research on Scanning Path Optimization of ER316 L Stainless Steel Arc Additive Manufacturing
In order to optimize the arc additive forming performance and improve the quality and efficiency of the addi-tive,it was studied that the arcs process parameters and the additive scanning path planning.On the basis of single-layer multi-pass and path lap forming experiments,the appropriate bead forming process parameters were determined.The zigzag path algorithm with different scanning angles was used to fill the model cross-section,and the deep-first search(DFS)algo-rithm was used to connect the arc starting and arc quenching points of the zigzag scan path partition,and the ant colony al-gorithm was further used to optimize the arc additive empty travel length.The experimental results showed that when the wire feed speed was 5 m/min,the optimal multi-channel lap spacing was 0.739w,and the compound path lap spacing was 0.577w.When the zigzag scanning angle was 135°,the DFS partition connection algorithm had the best optimization effect.The optimized scanning path planning algorithm could realize the stable additive forming of ER316 L sprocket model,at the same time,improve the forming accuracy and forming efficiency of formed parts.
