Precision turning with localized anodic dissolution

The basic principle of Electrochemical Machining is an anodic dissolution of metallic work pieces at their interface to a liquid ion conductor, called electrolyte, under the influence of electric charge transport. Electrochemical Machining with closed electrolytic free jet (Jet-ECM) is a new procedure which applies high current densities with a high degree of local removal, high localization of erosion and high surface quality [1]. Starting from this point machining of rotating work pieces by help of Jet-ECM is investigated [2]. Therefore a Jet-EC Turning prototype system was developed at Chemnitz University of Technology. In this study experimental investigations for a characterization of the influence of different process parameters on the Jet-EC turning result are presented.
