Applicability of Thin Coated Diamond Electrode Systems for Micro Die-sinking EDM

在本项目中，将研究、开发和应用新型耐磨薄涂层金刚石微沉模电极系统。与硬质合金、钨或钨铜等其他典型使用的材料相比，金刚石的显著优势是不存在材料转移造成的材料污染，是所有材料中最高的杨氏系数和低密度。这些优点使得大面积微结构金刚石箔和微棒和管电极的应用成为可能。其结果是澄清了有关材料科学、技术和设备的问题。项目建成后，可采用相关零件材料的高精度微沉模工艺技术。该项目的第二阶段侧重于微棒和管状电极的制造，以及关于微结构金刚石箔的直接单次制造和间接复制制造的工艺知识的积累。将详细说明技术图表，允许进行最佳磨损或最佳拆卸参数组合。这些图表还允许在有或没有电极振荡的情况下，使用金刚石薄涂层电极加工钢、陶瓷和硬质合金。

In this project, new wear resistant thin-coated diamond electrode systems for micro-die-sinking will be investigated, developed and applied. Significant advantages of diamond in comparison to the other typically used materials such as cemented carbide, tungsten or tungsten-copper are the non -existing material contamination by material transfer, the highest Youngs's modulus of all materials and the low density. These advantages enable the application of large-area micro-structured diamond foils and micro stick and tube electrodes. Result is the clarification of questions regarding materials science, technology and equipment. After the completion of the project, adopted process technologies for high precision micro die-sinking for relevant part materials are available. This second period of the project focusses on the manufacturing of micro stick and tube electrodes and the buildup of process knowledge regarding direct single-manufacturing and indirect replicative manufacturing of micro structured diamond foils. Technology charts will be elaborated, allowing for wear-optimal or removal-optimal parameter-combinations. The charts also allow for processes for machining steel, ceramics and cemented carbide with diamond thin coated electrodes with or without electrode oscillation.
