执行线放电加工（线-EDM）修剪切割操作以减小热影响区的厚度。机械要求高的应用，如具有高精度定位任务的柔性铰链，需要准确了解工件的热损伤水平。电子背散射衍射（EBSD）用于边缘区的全面表征。特别是可以详细分析晶粒尺寸和局部晶体取向。通过从根本上将局部晶体取向与来自线切割操作的标准X射线应力测量的残余应力分布相关联，未来将有可能以高分辨率局部确定工艺引起的损坏或改变层的厚度。然后，该信息可以用于优化柔性铰链精确运动运动学。
WireElectro Discharge Machining (Wire-EDM) trim cut operations are performed to reduce the thickness of the thermally influenced zone. Mechanically high demanding applications like flexure hinges with high precision positioning tasks need exact knowledge about the level of thermal damage in the workpiece. Electron Backscatter Diffraction (EBSD) is used for a comprehensive characterization of the rim zone. Especially grain sizes and local crystal orientations can be analyzed in detail. By fundamentally correlating the local crystal orientation with the residual stress distributionsfrom standardX-ray stress measurements for Wire-EDM operations, it will be possible in future to determine locally the thicknesses of the process induced damaged or altered layers with high resolution. This information can then be used to optimize the flexure hinge precision movement kinematics.
