由于玻璃和陶瓷材料具有相对低的摩擦、高的抗压强度、耐高温和耐磨性以及优异的化学惰性等特点，工业应用得到了多方面的发展。在微机电系统中，玻璃、硅和聚合物的使用已经变得非常流行。然而，玻璃的微加工是一个困难的过程。电解放电加工是目前常用的无屑加工方法之一。电化学放电加工是一个多参数可控的复杂过程，具有随机性。尽管有许多理论，但在这一过程中材料去除的机理尚未得到很好的理解。本文试图建立电化学放电加工钻孔材料去除的三维有限元模型，进一步探讨其机理，并将研究结果与实验结果相联系。将模型输出结果与文献中的实验结果进行了比较。模型计算结果与试验结果吻合较好。
Industrial applications of glass and ceramic materials have increased manifold due to their relatively low friction, high compression strength, high temperature and wear resistance, and excellent chemical inertness, etc. In microelectromechanical systems the use of glass, along with silicon and polymer, has become very popular. However, microfabrication of glass is a difficult process. The electrochemical discharge machining is now often used as one of the chipless machining solutions for these materials. The electrochemical discharge machining, however, is a complex process with multiple controllable parameters and exhibits stochastic nature. The mechanism of material removal in the process is yet to be understood well in spite of many theories. In this paper, an attempt has been made to develop a three-dimensional finite element model for simulation of material removal in electrochemical discharge machining drilling in order to explore the mechanism further and correlated the findings with the experimentally obtained values. The model outputs were compared with experimental results available in literature. The computed results from the model show good agreement with the trial results.
