Models are useful in controlling the process effectively and efficiently in micro electro discharge machining (Micro-EDM). There are two types of models which are empirical models and theoretical models. Most of the models are basically formulated for conductive work materials. However, nowadays there is a trend to cut nonconductive materials using micro-EDM where the models developed for conductive materials are not applicable. There are only few models that are developed to cut nonconductive materials with micro EDM but these models have limitations. In this article, models for cutting conductive materials and nonconductive materials using micro EDM are compared in view of their applications.

模型有助于在微放电加工 (Micro-EDM) 中有效和高效地控制过程。有两种类型的模型，即经验模型和理论模型。大多数模型基本上都是为导电工作材料制定的。然而，现在有一种趋势是使用微电火花切割非导电材料，而为导电材料开发的模型并不适用。开发用于使用微型 EDM 切割非导电材料的模型很少，但这些模型具有局限性。在本文中，针对使用微电火花加工切割导电材料和非导电材料的模型，针对它们的应用进行了比较。
