摘要/Abstract

摘要： 为了提高工件材料蚀除的定域性，对裸阴极、侧壁绝缘阴极和缩进阴极进行了研究.以阴阳两极间电解液为研究对象，建立电场模型，通过数值模拟获得加工间隙中电位和电流密度分布，研究阴极结构对微孔进口形状精度的影响.根据模拟结果，分析缩进阴极电解加工微孔时，工艺参数对加工精度和加工效率的影响，优选最佳工艺参数.结果表明，采用优选参数缩进深度50μm，加工电压5V，进给速度3μm/s，能获得良好的加工精度.

Abstract: In order to improve the material removal localization of workpiece, uninsulated tools, sideinsulated tools and retracted tip tools are investigated. Electrolyte between anode and cathode is the main research object in the paper. Computational models of electric field are developed, and the distribution of electric potential and current densities in the machining gap are obtained through numerical simulation method. By the numerical results the effects of using retracted tip tools on entrance quality are researched. Furthermore, effects on machining accuracy and efficiency of using retracted tip tools are analyzed, and optimum parameters are obtained based on the simulation results. Results show that good machining accuracy can be obtained with the optimum parameters that retracted tip depth is 50μm, machining voltage 5V and feed rate 3μm/s.

Key words: electrochemical micromachining, retracted tip tool, numerical simulation of electric field
