摘要：

Ti-6Al-4V is a typical difficult-to-cut material with which it is difficult to achieve a high processing efficiency and good surface quality simultaneously using a single processing method. In this paper, a combined method that consists of electrochemical milling and grinding is proposed to solve this problem. Two types of electrodes were used in the different machining stages. First, the polarization curves for Ti-6Al-4V in 10% NaNO3 solution were obtained. Then, the maximum feed and material removal rates were studied using various electrochemical milling parameters. The resulting machined groove cross-sectional profiles were compared. Finally, the effects of electrochemical grinding on the machining results were investigated. The machined workpiece surfaces were examined using scanning electron microscopy and their roughnesses were measured using a roughometer.
