适当选择制造条件是导电陶瓷的电火花成型加工（EDM）中需要考虑的最重要方面之一，因为这些条件是决定表面粗糙度、电极磨损（EW）和材料去除率等重要特性的条件。在这项工作中，进行了研究的影响因素的强度（I），脉冲时间（t（i））和占空比（eta）在列出的技术特性。本研究中使用的陶瓷是硬质合金或硬质金属，例如94 WC-6Co。大约50%的硬质合金产品用于机加工应用，但硬质合金也越来越多地用于非机加工应用，例如：采矿，石油和天然气钻探，金属成形和林业工具。因此，数学模型将获得使用的实验设计（DOE）的技术，以选择最佳的加工条件，精加工阶段。这将只使用少量的实验来完成。(C)2004 Elsevier B.

The adequate selection of manufacturing conditions is one of the most important aspects to take into consideration in the die-sinking electrical discharge machining (EDM) of conductive ceramics, as these conditions are the ones that are to determine such important characteristics as: surface roughness, electrode wear (EW) and material removal rate, among others. In this work, a study was carried out on the influence of the factors of intensity (I), pulse time (t(i)) and duty cycle (eta) over the listed technological characteristics. The ceramic used in this study was a cemented carbide or hard metal such as 94WC-6Co. Approximately 50% of all carbide production is used for machining applications but cemented carbides are also being increasingly used for non-machining applications, such as: mining, oil and gas drilling, metal forming and forestry tools. Accordingly, mathematical models will be obtained using the technique of design of experiments (DOE) to select the optimal machining conditions for finishing stages. This will be done only using a small number of experiments. (C) 2004 Elsevier B.V. All rights reserved.
