Electrochemical machining with continuous electrolytic free jet for the generation of micro geometries in steel materials

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，将研究平坦表面的喷射-EC加工的可转换性，这是前一个资助期的结果，到旋转对称的工件几何形状。除了平面加工的可转移性外，还应分析喷嘴和工件之间较高的相对速度对加工结果的影响。由于旋转运动可以将相对速度提高到几倍，根据平面加工中的分析，可以显著降低粗糙度。首先，在适当的工艺输入参数的变化下，通过系统的Jet-EC仿形车削实验，分析了单次去除的几何形状。之后，应通过改变单个清除器的相互作用程度来进行Jet-EC圆柱形车削的系统试验。在平面加工研究的基础上，分析了其对去除几何形状的影响。

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.
