电火花加工 (edm) 中的金属去除基本上是一种热腐蚀过程，其中热传递主要通过传导进行。本文采用二维传热模型，假设等离子体通道为圆盘热源，用于研究电火花加工输入参数（例如脉冲持续时间、脉冲能量和材料特性）对金属去除和火山口形状的影响。讨论了理论数据和实验数据之间相关性较差的原因。
Metal removal in electro-discharge machining (edm) is basically a thermal erosion process where the heat transfer is predominantly through conduction. In this paper, a two-dimensional heat transfer model, assuming the plasma channel to be a disc heat source, has been employed to study the effects of edm input parameters, such as pulse duration, pulse energy and material properties, on metal removal and crater shape. Reasons for somewhat poor correlation between theoretical and experimental data are discussed.
