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导致工件几何形状的特定变化，通常金属材料被加工。在这项研究中，应检查平面喷射EC加工的可转移性，这是前一个资助期的结果，旋转对称工件几何形状。除了加工平面的可转移性外，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。由于旋转运动可以使相对速度提高几倍，因此根据加工平面表面的分析，期望显著降低粗糙度。首先，借助于在适当的工艺输入参数变化下的Jet-EC轮廓车削的系统实验，分析单次去除的几何形状。然后，应通过改变单个去除的相互作用程度来进行Jet-EC圆柱车削的系统实验。在此基础上，分析了平面加工中切削参数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.
