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 transferability of jet-EC machining of flat surfaces, which was the outcome of the previous funding period, onto rotationally symmetric work-piece geometries shall be examined. In addition to the transferability of machining planar surfaces, the impact of higher relative speeds between the nozzle and the work-piece on the machining result shall be analyzed. Since the relative speed can be increased to several folds applying a rotary motion, a significant reduction in roughness is aspired according to the analyses in machining planar surfaces.At first, the geometry of single removals shall be analyzed by help of systematic experiments in Jet-EC profile turning under the variation of suitable process input parameters. Afterwards, systematic experiments in Jet-EC cylindrical turning shall be performed by varying the degree of interaction of the single removals. Thereby the influence on the removal geometry is analyzed based on the studies in machining planar surfaces.

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发生特定变化。在本研究中，应检查平面喷射 EC 加工（这是上一资助期的成果）到旋转对称工件几何形状的可转移性。除了加工平面的传递性外，还应分析喷嘴与工件之间较高的相对速度对加工结果的影响。由于旋转运动的相对速度可以增加几倍，因此根据加工平面的分析，希望显着降低粗糙度。首先，应在适当的工艺输入参数变化的情况下，通过 Jet-EC 仿形车削的系统实验来分析单次去除的几何形状。随后，应通过改变单次切削的相互作用程度来进行 Jet-EC 外圆车削的系统实验。从而基于平面加工的研究分析了对去除几何形状的影响。
