Electrical discharge machining (EDM) is an advanced machining method which removes metal by a series of recurring electrical discharges between an electrode and a conductive workpiece, submerged in a dielectric fluid. Even though EDM techniques are widely used to cut hard materials, low efficiency and high tool wear remain remarkable challenges in this process. Various studies, such as mixing different powders to dielectric fluids, are progressing to improve their efficiency. This paper reviews advances in the powder-mixed EDM process. Furthermore, studies about various powders used for the process and its comparison are carried out. This review looks at the objectives of achieving a more efficient metal removal rate, reduction in tool wear, and improved surface quality of the powder-mixed EDM process. Moreover, this paper helps researchers select suitable powders which are exhibiting better results and identifying different aspects of powder-mixed dielectric fluid of EDM.
电火花加工（EDM）是一种先进的加工方法，它通过浸没在介电流体中的电极与导电工件之间一系列反复的放电来去除金属。尽管电火花加工技术被广泛用于切割硬质材料，但在这个过程中，低效率和高刀具磨损仍然是显著的挑战。各种研究，如将不同粉末混入介电流体中，正在进行以提高其效率。本文综述了粉末混合电火花加工工艺的进展。此外，还对该工艺中使用的各种粉末及其比较进行了研究。这篇综述着眼于实现更高的金属去除率、减少刀具磨损以及改善粉末混合电火花加工工艺表面质量的目标。此外，本文有助于研究人员选择表现出更好效果的合适粉末，并识别电火花加工粉末混合介电流体的不同方面。
