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.

本计画将研究、开发及应用新型耐磨薄涂层金刚石微冲切电极系统。与其他常用材料（如硬质合金、钨或钨铜）相比，金刚石的显著优点是不存在由材料转移引起的材料污染、所有材料中最高的杨氏模量和低密度。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。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电极的制造以及关于微结构金刚石箔的直接单一制造和间接复制制造的工艺知识的积累。技术图表将详细说明，允许最佳磨损或最佳移除参数组合。该图表还允许在有或没有电极振荡的情况下用金刚石薄涂层电极加工钢、陶瓷和硬质合金的工艺。
