“…Combining electrical discharges and ultrasonic-assisted mechanical means is an ideal method suitable for PCD materials. 58 The effects of the EDM combined with the ultrasonic vibration for machining Si 3 N 4 were investigated. 59 MRR of the UVAEDM was about two times higher than that for the normal EDM for the range of the ultrasonic frequency between 17 and 25 kHz.…”

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.

“…The investigation on the machinability of PCD would greatly important as it plays important role in several aforementioned extreme applications. Since 2010 extensive research has been initiated to increase PCD machining efficiency and tool quality [1,2] But no significant breakthrough was achieved due to the lack of innovative approaches and new theories to solve the two fundamental problems in machining PCD: the ultra-hardness of diamond particles and the low electrical conductivity of PCD material. Despite improvements of various levels were achieved, the increase in machining efficiency was limited.…”

“…Due to high hardness of PCD, only diamond grinding wheels can be applied in PCD grinding [2]. However, it suffers with high wheel wear (G ratio of 0.01 to 0.05) and extremely low material remove rate [1,5] This leads to the high manufacturing cost caused by the long machining time that becomes a major impediment to the implementation of PCD tools: a brazed PCD tool is about 10 times expensive than a tungsten carbide tool, and the price of a vined PCD tool is about 20 times higher than the carbide ones Electrical Discharge Machining (EDM) is a noncontact thermal erosion process in which the metal is removed by a series of recurring electrical discharges between the electrode and the electrically conductive workpiece, in the presence of a dielectric fluid.…”

“…Ultrasonically aided electrical discharge machining (EDM+US) could be a competitive response of all these, in terms of machining rate, precision and surface quality in relation with manufacturing costs [5]. Other advanced materials, difficult to process with other means, were machined by EDM+US with spectacular increase of main technological performances [6,7,8], but no reported references for CoCr alloys yet [9].…”

Abstract. The paper deals with researches of microtopography obtained at different working modes at ultrasonically aided micro-electrical discharge machining (µEDM+US) and pure micro-EDM, using both commanded and relaxation pulses. Images of machined surface taken with scanning electron microscope were analyzed in correlation with chemical composition of samples detected by X rays spectrometer. This led to some explanations of material removal mechanism, aiming at improvement of process modelling and performances increase of µEDM+US.
