Abstract:

A reasonable process plan is an important basis for implementing wire arc additive and subtractive hybrid manufacturing (ASHM), and a new optimization method is proposed. Firstly, the target parts and machining tools are modeled by level set functions. Secondly, the mathematical model of the additive direction optimization problem is established, and an improved particle swarm optimization algorithm is designed to decide the best additive direction. Then, the two‑step strategy is used to plan the hybrid manufacturing alternating sequence. The target parts are directly divided into various processing regions; each processing region is optimized based on manufacturability and manufacturing efficiency, and the optimal hybrid manufacturing alternating sequence is obtained by merging some processing regions. Finally, the method is used to outline the process plan of the designed example model and applied to the actual hybrid manufacturing process of the model. The manufacturing result shows that the method can meet the main considerations in hybrid manufacturing. In addition, the degree of automation of process planning is high, and the dependence on manual intervention is low.

合理的工艺方案是实施电弧增减材混合制造的重要基础，提出了一种新型电弧增减材混合制造工艺优化方法。首先，利用水平集函数对目标零件和加工工具建模。其次，建立目标零件增材方向优化问题数学模型，并设计了改进粒子群优化算法以决策出最佳增材方向。然后，采用两步走策略规划目标零件的增减材混合制造交替序列，先直接将目标零件划分成各加工区域，再在考虑可制造性和制造效率的基础上优化各加工区域，并通过对加工区域的合并得到最佳混合制造交替序列。最后，采用该方法规划了所设计实例模型的工艺方案，并将其运用到模型的实际混合制造过程中。制造结果表明，该方法基本能够满足混合制造中的主要考虑点，且工艺规划过程自动化程度也较高，对人工干预的依赖较少。
