摘要
文中根据电化学加工原理,以金属电化学线切割缝宽模型作为切割效果评价标准,分析得出影响缝宽变化的工艺参数,主要有加工电压和工具电极丝进给速度。在此基础上考察参数变化对缝宽的影响,同时参考切割时的电流效率对参数进行优化,获得具有较高精度和表面质量的切割工件毛坯。
A side width model of metal wire electrochemical cutting as an evaluation criterion of cutting effects is presented in this study. Side width change is mainly affected by voltage and feeding speed of tool cathode. Changes in the side width according to parameters were investigated. The optimal parameters were obtained by analyzing this changes and consuhing current efficiency. By using the optimal technological parameters, parts sort of high precision and surface quality were fabricated.
