在简要回顾了 EDM 及其在先进航空航天合金（包括工件完整性约束）上的应用后，提供了加工 Ti-6Al-4V 和 Inconel 718 后的数据。在两台高规格机床上采用了粗加工和精加工（多次修剪切削）策略，并配有脉冲发生器，旨在最大限度地减少工件完整性损坏。结果包括生产率、工件表面的 3D 形貌图、显微结构和显微硬度深度剖面数据。平均重铸厚度为
Following a brief review of EDM and its use on advanced aerospace alloys including workpiece integrity constraints, data are presented after machining Ti-6Al-4V and Inconel 718. Roughing and finishing (multiple trim cut) strategies were employed on two high specification machines with pulse generators designed to provide minimum workpiece integrity damage. Results include productivity, 3D topographic maps of workpiece surfaces, microstructural and microhardness depth profile data. Average recast thickness was
