Abstract
Electrolyte jet electrochemical turning (ECT) is an effective method to realize high-quality machining of rotating components made by titanium alloy. However, very few studies have been carried out in this field, which may be attributed to the difficulty in flow field control and hence the associated poor machining surface quality. In this work, numerical simulations were conducted to optimize the machining flow field and reduce the proportion of gas that mixed into the machining area. This can promote participation of the tool electrode tip in the electrochemical reaction and improve the machining efficiency. The effectiveness of the optimized machining flow field for jet electrochemical turning was verified experimentally on three kinds of revolving TB6 titanium alloy samples with different structures. After machining, the original contour shape is maintained, while the contour error is less than 1% and the surface roughness is around Ra 2.414 μm. The results demonstrate the application potential of the jet electrochemical turning process.
