Experiment Study on Micro-Cylindrical Electrode Fabrication in Electrochemical Machining

Abstract

Aiming at the key techniques in ECM, the ECM system has been developed. The micro-tool-electrode and workpiece have been machined on the machine tool. Base on the experiment analysis of the effect of voltage, immersion depth, power characteristics on its forming laws in the micro-tool-electrode machining, the ECM has been realized in low concentration alkaline electrolyte. A micro-tool-electrode with the length of 1200 um, the diameter of 16 um, and aspect ratio of 75:1 has been machined by the developed machine tool.
