“…The up-down movement of the tool causes the cavitation to take place mostly on the adjacent tool surface, therefore enhances the tool wear ratio with the addition of UVA [105]. However, Jiang et al reported on the improved tool wear rate due to the improved gap status and weakened tool erosion [87]. A similar observation was reported by Tong et al during ultrasonic vibration (workpiece) assisted micro-EDM.…”

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.

Ultrasound waves are directly being used in many of the industrial applications including material removal for generating profiles on material surfaces. Trend has been shifted to use ultrasonic sound waves or ultrasonic vibrations as assisting media to enhance process performance. Electric discharge machining is one such industrial application for material removal, where ultrasonic vibrations have been introduced as assisting media for improving process performance. Ultrasonic vibrations were mainly employed in electric discharge machining process for improved debris evacuation from the sparking gap to increase process efficiency. It also resulted in stable and consistent sparking sequences by minimizing adverse arcing phenomenon in electric discharge machining. Since its introduction, technology of ultrasonic assistance in electric discharge machining has gone through considerable changes and penetrated to various variants of the electric discharge machining process mainly die sinking electric discharge machining, wire cut electric discharge machining and micro electric discharge machining.This article presents a research review for applications of ultrasonic vibrations for electric discharge machining process. The review has been carried out in terms of modes of applying ultrasonic vibrations, effect on performance parameters, process modelling and optimization and application for difficult-to-cut advanced materials. Based on the review of present status of the ultrasonic-assisted electric discharge machining, future research needs have been identified to strengthen the capacity and capabilities of the electric discharge machining process.

“…But the vibration exciter of the ultrasonic device is often manufactured within a narrow frequency range, thereby the vibration frequency is hard to be adjusted. Currently, a vibration platform for small-hole EDM based on voice coil motor (VCM) was developed [9], it is capable of avoiding the easy loss of vibration energy and the heat effect in ultrasonic vibration, and the machining efficiency was significantly improved, compared to the normal smallhole EDM. However, the vibration platform based on VCM makes the workpiece vibrates, rather than the electrode in the machining process, so it is hard to drill the inclined holes.…”

To address the problem of debris accumulation in small-hole electrical discharge machine (EDM) and simplify the design of the spindle head, the paper proposes a novel composite motion design procedure integrated high frequency vibration and large stroke feed using one voice coil motor (VCM). Particularly, for the purposes of high servo accuracy and high frequency response of the composite motion, an improved zero-phase-error tracking controller (ZPETC) algorithm decoupled with the feedback controller is developed for the process control, in which the feedback parameter adjustment is very simple to reduce the computation complexity. At last, the proposed procedure is validated by the experimental study of the established VCM positioning table; the results verify the efficiency of the proposed method.
