摘　　要：基于不同材质电极在电火花加工过程中损耗速率的差异,提出了放电蚀除策略,构建了多材质叠层电极电火花加工微结构三维仿真模型,分析了工件表面微结构在加工过程中的形貌演变,为探究电极材质构成、梯度设计提供依据,指导工件表面微结构的成形加工。此外,进行了两种典型表面微结构(Cu、Sn叠层和CuSn叠层)的电火花加工实验,得出实际加工与仿真数据的相对误差分别为6.4%和4.8%,表明仿真模型具有较高的准确度和广泛的通用性。Based on the difference in wear rates of electrode with different materials in electrical discharge machining(EDM),a multi-material electrodes electrical discharge erosion strategy was proposed.Based on this strategy,a three-dimensional(3D) simulation model of EDM with multi-material laminated electrodes was established,and the morphological evolution of surface microstructures on the workpiece during processing was analyzed,which provided a foundation for investigating the composition of electrode materials and gradient design,thereby guiding the formation processing of microstructures on the workpiece surface.In addition,EDM experiments were conducted on two typical surface microstructures(Cu and Sn laminated layers and CuSn laminated layers).It was found that the relative errors between the actual machining and simulation data were 6.4% and 4.8% respectively,indicating that the simulation model has high accuracy and wide universality.
