Abstract
Ultrasonic-assisted jet electrochemical micro drilling is an advanced variant of electrochemical machining to drill micro holes quickly and efficiently. The present article deals with the modelling and simulation of the integration of ultrasonic vibration with the conventional jet electrochemical micro drilling process. Multi-physics-based modelling and simulation approach has been used in the present work. The flow pattern of electrolyte jet was analysed for both jet electrochemical micro drilling and ultrasonic-assisted jet electrochemical micro drilling processes. The simulation results were validated with the previous experimental findings of ultrasonic-assisted jet electrochemical micro drilling process. It was found that the material removal rate (MRR) improved significantly as the ultrasonic wave got superimposed onto the electrolyte jet. In addition to that, voltage and concentration of the electrolyte also played vital roles in improving the MRR.
