As shown in Fig. 3 a, the small holes are machined by ultrasonic-assisted electrochemical drill-grinding set up. While the ball-end electrode rotates continuously, it is accompanied by downward feeding and periodic vibration. It can be seen that the ball-end electrode is equipped with diamond abrasive particles, which are added to the ball-end …

The grinding wheel feed rate ranged from 1.2 mm·min −1 to 1.8 mm·min −1, equally divided into four intervals. When the grinding wheel feed rate was too slow, the rate of electrochemical material removal was too slow, and when the grinding wheel feed rate was too fast, it was unable to continue the process due to frequent short circuits.
