Optimization of Ultrasonic Assisted Electro-discharge Machining Process Parameters Through Surface Response

This work aim to optimize the factors using the ultrasonic vibration generator for the EDM. The performance namely surface roughness, in the EDM, calls for a refined assessment of the input factors. In this study, the experiment was conducted with shape memory alloy with ultrasonic vibration. This paper describes an attempt to apply low-frequency vibration on a shape memory alloy (NiTi) workpiece during the EDM process. The workpiece was vibrated with low frequency and low amplitude fluctuations. The results suggest that using low-frequency vibration in the EDM process can decrease surface roughness. The experiment was carried out, and the outcomes were examined utilizing statistical approaches such as the response surface methodology. For analysis L32 orthogonal array was used. Finally, from the statistical technique, optimum process parameters are calculated and validated experimentally.
