In electrochemical machining (ECM) an anodic dissolution of electrical conductive material causes a specific change of the work piece geometry, where usually metallic materials are machined. In this study the possibility of designing EC process or process chains for machining carbide-based materials shall be examined. Thereby, processes of shaping, imaging and finishing are to be examined theoretically and experimentally. Furthermore, the applicability of machining carbide-based materials shall be analyzed and evaluated. To overcome nontrivial surface oxidation inhibiting the anodic dissolution, secondary fluid dynamic and electrical processes are used for the process support.The goal of this project is to develop a tool and process system for producing complex structures in carbide-based materials using electrochemical manufacturing processes.

在电化学加工(ECM)中，导电材料的阳极溶解会导致通常加工金属材料的工件几何形状的特定变化。在这项研究中，应研究设计加工硬质合金材料的EC工艺或工艺链的可能性。因此，对成形、成像和精加工过程进行了理论和实验研究。并对硬质合金材料的加工适用性进行了分析和评价。为了克服表面氧化对阳极溶解的抑制作用，二次流体动力学和电学工艺被用于工艺支持。本项目的目标是开发一种利用电化学制造工艺来制造碳化物基材料中复杂结构的工具和工艺系统。
