由于电火花加工可以提供高精度和良好的表面质量，因此它可能成为制造微型工具、微型组件和具有微型特征的零件的重要工艺。然而，在微细放电加工成为具有可重复结果的可靠工艺并实现其作为微制造技术的全部功能之前，仍有许多问题需要解决。本文介绍了各种形式的微细电火花加工（线切割、钻孔、铣削和开模）的最新进展，并讨论了主要研究问题。本文重点讨论了电火花加工工艺的规划和电极磨损问题。特别关注影响可达到的精度的因素和程序，包括电火花加工和电极磨削期间的定位方法。 (C) 2004 Elsevier B.V. 保留所有权利。
Due to the high precision and good surface quality that it can give, EDM is potentially an important process for the fabrication of micro-tools, micro-components and parts with micro-features. However, a number of issues remain to be solved before micro-EDM can become a reliable process with repeatable results and its full capabilities as a micro-manufacturing technology can be realised. This paper presents some recent developments in micro-EDM in its various forms (wire, drilling, milling and die-sinking) and discusses the main research issues. The paper focuses on the planning of the EDM process and the electrode wear problem. Special attention is paid to factors and procedures influencing the accuracy achievable, including positioning approaches during EDM and electrode grinding. (C) 2004 Elsevier B.V. All rights reserved.
