摘要: 以钛合金电解加工圆孔为对象,充分考虑加工中电场与移动网格相互关系建立了圆孔加工理论模型,采用数值计算方法得到了电解加工圆孔电位分布、电流密度分布、成形过程和材料变化,探讨了不同加工参数(脉冲平均电压、电导率和进给速度)对电解加工圆孔成形的影响,并开展了电解加工圆孔实验,得到了圆孔形貌,在相同加工参数下,理论计算和实验得到的圆孔深度分别1.07mm和1.157 14mm,两者能够较好地吻合,可为电解加工圆孔提供理论依据。

Abstract: Taking circular hole electric chemical machining(ECM) as an object, a theoretical model of circular hole was established by taking into account the mutual relationship of electric and moving mesh in process. The distributions of circular hole potential and current density, forming process and material changes were obtained by using numerical methods, the relationship among different processing parameters(the average voltage pulse, the electrical conductivity, the feed rate)and circular hole forming was discussed, And the circular hole ECM tests were done. According to the same processing parameters, circular hole theoretical depth 1.07mm is a better match circular hole experimental depth 1.157 14mm,thus it provides a theoretical basis for circular hole ECM.

Key words: titanium alloy;circular hole, moving mesh, processing parameter
