چکیده مقاله
This paper deals with the effect of copper tool vibration with ultrasonic US frequency on the electrical discharge machining EDM characteristics of tungsten carbide WC Co It is found that ultrasonic vibration of the tool USVT is more effective in attaining a high material removal rate MRR in low current and low pulse time finishing regimes , and in general the surface roughness and tool wear ratio TWR increase It is observed that ultrasonic vibration of the tool significantly reduces arcing and open circuit pulses, and the stability of the process is increased This study shows that, there are optimum conditions for ultrasonic assisted machining of tungsten carbide,although the conditions may vary by giving other input parameters for those which have been set constant in the present work
