电解加工（ECM）的加工潜力越来越被人们所认识，而加工轮廓的精度是其应用的一个关注点。分析了在金属表面腐蚀出数百微米孔的过程。提出了一个理论和计算模型，以说明如何加工的轮廓随着时间的推移而演变。分析是基于电解的基本规律和有限宽度工具的积分。讨论了电解时间、电解电压、电解液摩尔浓度和电极间隙等实验参数对材料去除量和加工孔直径的影响。实验结果表明，材料去除率随电压、电解液摩尔浓度、电解时间的增加和初始间隙的减小而增加。电解时间是影响孔直径的主要因素。(C)2003 Elsevier B.V.保留所有权利。
Electrochemical machining (ECM) has been increasingly recognized for the potential for machining, while the precision of the machined profile is a concern of its application. A process to erode a hole of hundreds of micrometers on the metal surface is analyzed in the current paper. A theoretical and computational model is presented to illustrate how the machined profile evolves as the time elapses. The analysis is based on the fundamental law of electrolysis and the integral of a finite-width tool. The paper also discusses the influence of experimental variables including time of electrolysis, voltage, molar concentration of electrolyte and electrode gap upon the amount of material removal and diameter of machined hole. The results of experiment show the material removal increases with increasing electrical voltage, molar concentration of electrolyte, time of electrolysis and reduced initial gap. The time of electrolysis is the most influential factor on the produced diameter of hole. (C) 2003 Elsevier B.V. All rights reserved.
