摘要

在目前的工作中，研究了变压器油作为电火花加工(EDM)介质在铬镍铁合金825电火花加工(EDM)中的适用性，并与常规电火花加工介质(EDM油)进行了比较。加工性能在材料去除效率的范围内进行评估。研究了变压器油(作为电介质)加工表面的形貌和形貌特征。表面形貌研究包括表面粗糙度、材料迁移、相分析以及外来元素的迁移。与电火花加工油相比，变压器油具有更高的材料去除率和更好的表面光洁度。峰值电流的增加导致材料去除率、表面粗糙度、表面裂纹密度和白层厚度的增加。

Machinability Appraisement of Inconel 825 during Electro-Discharge Machining: Use of Transformer Oil as Dielectric Media

In the present work suitability of transformer oil to be used as dielectric media during Electro-Discharge Machining (EDM) of Inconel 825 is studied in comparison with conventionally used dielectrics i.e. EDM oil. Machining performance is evaluated in purview of material removal efficiency. Morphology and topographical features of the machined surface produced by using transformer oil (as dielectrics) are studied. Surface topographic studies include surface roughness, material migration, phase analysis as well as immigration of foreign elements. It is observed that as compared to EDM oil, transformer oil offers higher material removal rate and superior surface finish. It is also observed that increase in peak current causes increased material removal rate, surface roughness, surface crack density and white layer thickness.
