摘　　要：针对复杂钣金加工工艺规划研究存在的不足,以空调钣金外壳作为研究对象,阐述了空调钣金的特征,分析了具有相同加工的组合特征和特征间的相互约束,建立了特征的约束模型。在特征加工方案和约束模型基础上建立钣金工艺规划模型,运用遗传算法对问题进行分析求解,并采用蚁群算法对组合特征的加工路线进行优化,给出算法的原理和步骤。最后通过仿真实验验证了该方法的可行性与有效性,可以有效提高钣金外壳加工效率。In view of the shortcomings of the research on the process planning of complex sheet metal, this paper takes the sheet metal shell of air conditioner as the basic research object, expounds the characteristics of the sheet metal of air conditioner, analyzes the combined features with the same processing and the mutual constraints between features, and establishes the constraint model of features.On the basis of feature processing scheme and constraint model, a sheet metal process planning model is established. Genetic algorithm is used to analyze and solve the problem. Ant colony algorithm is used to optimize the processing route of combined features. The principle and steps of the algorithm are given. Finally, the feasibility and effectiveness of the method are verified by simulation experiments. This method can effectively improve the processing efficiency of sheet metal shell.
