Abstract

Wire Electrical Discharge Machining (Wire EDM) is particularly suitable for producing high-precision geometries in demanding materials such as the manufacture of profile grooves in turbine disks. Advanced monitoring nowadays allows the time and spatially resolved in-process discharge analysis. Therefore, in this paper the machining of Inconel 718 parts is fundamentally studied and the resulting surface integrity in terms of roughness and residual stresses is evaluated for main and trim cut strategies. Finally, the resulting bending fatigue performance is characterized in a zone resolved and overall averaged analysis along the workpiece height and compared to reference results of alternative machining approaches.

空间分辨电火花线切割放电分析用于动态零件强度评估

线材电火花加工（Wire EDM）特别适合在要求苛刻的材料中生产高精度几何形状，例如涡轮盘的轮廓槽的制造。现在先进的监测允许时间和空间分辨过程中的放电分析。因此，本文对Inconel 718零件的加工进行了基本的研究，并对主要切削策略和切边切削策略的表面粗糙度和残余应力进行了评估。最后，通过区域分解和沿工件高度的整体平均分析来表征弯曲疲劳性能，并与替代加工方法的参考结果进行比较。
