Abstract
Many of the industrial processes, including material removal operation for shape generation
on the surface of material, exploit the assistance of ultrasonic vibrations. This trend of using
ultrasonic vibration in order to improve the process performance is becoming more and more
prominent recently. One of the significant applications of this ultrasonic vibration is in the industrial
processes such as Electro-discharge machining (EDM), where ultrasonic vibration (UV) is inserted
as a medium for enhancing the process performance. Mostly ultrasonic vibration is applied along
with the EDM process to increase the efficiency of the process through debris cleansing from the
sparking gap. There have been significant changes in ultrasonic assisted technology during the
past years. Due to its inherent advantages, ultrasonic assistance infiltrated in different areas of
EDM, such as wire cut EDM, micro EDM and die sinking EDM. This article presents an overview of
ultrasonic vibration applications in electric discharge machining. This review provides information
about modes of UV application, impacts on parameters of performance, optimization and process
designing on difficult-to-cut materials. On the bases of available research works on ultrasonic
vibration assisted EDM, current challenges and future research direction to improve the process
capabilities are identified. Literature suggested improved material removal rate (MRR), increased
surface roughness (SR) and tool wear ratio (TWR) due to the application of ultrasonic vibration
assisted EDM. However, tool wear and surface roughness can be lessened with the addition of carbon
nanofiber along with ultrasonic vibration. Moreover, the application of ultrasonic vibration to both
tool and workpiece results in higher MRR compared to its application to single electrode.
