摘　　要：化学铣切生产线是航空航天工业应用广泛的加工工艺,它可以对多种金属材料进行加工,对于一些加工精度较高的零件有很好的加工效果.在化铣加工中,零件每次经过槽液处理,槽液的离子浓度都会有较大的损失,造成槽液的频繁更换,不仅浪费资源,而且会对环境造成污染.本文是依据系统动力学知识,对化铣线槽液建立仿真模型,并通过实际数据验证了模型的可行性,同时对化铣线提出改进方案,通过对比改进前后槽液指标的变化,证明了改进方案的有效性,达到了减少槽液损失,延长槽液使用时间的目的.Chemical milling is a widely used processing technology in the aerospace industry.It can process a variety of metal materials and has good processing results for some parts with high processing precision.In the process of chemical milling,each time the parts are processed through the bath,the ion concentration of the bath will be greatly lost,resulting in frequent replacement of the bath,which not only wastes resources,but also pollutes the environment.Based on the knowledge of system dynamics,this paper establishes a simulation model for the slotting fluid of the milling and milling machine,and verifies the feasibility of the model through actual data.At the same time,it proposes an improved scheme for the milling and milling line,and proves the change of the groove index before and after the improvement.The effectiveness of the improved scheme achieves the purpose of reducing the loss of the bath and prolonging the use time of the bath.
