“…They also reported lesser overcut and significantly reduced HAZ formation, compared to conventional ECSM. In a study, [70] found that triplex hybridization (such as vibration, magnetic, rotary tool electrode assisted) of the ECDM process is the most efficient way to machine difficult-to-cut materials [71]. Micromachining of ceramics was also performed using ECDM [72].…”

There has been an increasing interest in the penetration of magnetic field-assisted machining processes in the industries. Due to the ease of contactless forces, magnetic fields have proved extremely versatile and relatively low cost when considering the potential increase in productivity of existing machining processes that it can provide. In this overview, we review the recent achievements and developments in magnetic field-assisted machining processes and their applications. A wide variety of machining domains are examined including electro-discharge machining (EDM), micro-EDM, electrochemical machining, magnetic-assisted machining and many more. The advantages and limitations of each implementation and potential future research pathways are also discussed.

“…Chavoshi and Behagh [10] investigated and discussed the hole length and axial wear parameters and relation between them. That results were cited from the paper by Coteate [11]. The influences of process parameters of ECDM on MRR were researched for borosilicate glass and process parameters were optimized using Taguchi's method by Paul and Hiremath [12].…”

“…Spring-fed cylindrical hollow brass tool and spring-fed cylindrical abrasive tool were used to drill aluminium oxide (Al2O3). Coteate et al emphasized the effects of some parameters (the voltage, the electrode tool diameter and the work liquid density) on the electrode tool wear [24], the effects of the input parameters on the tool wear and on the drilling speed [25], the effects of the voltage, the capacity of electric circuit on tool wear [11]. They also designed, built and tested an in-house equipment on ECDD process with passivating electrolyte [26].…”

In this study, progress and sort of electrochemical discharge machining (ECDM) that was developed to manufacture the micro features like micro grooves, micro pillar, micro holes and micro channels etc. were investigated. Many materials can be machined regardless of material conductivity, hardness and strength by ECDM using electro chemical machining (ECM) and electric discharge machining (EDM) combination. Researchers developed electrochemical discharge drilling (ECDD), turning (ECDT), grinding (ECDG), milling, dressing, trepanning, wire ECDM, die-sinking ECDM, rotary ECDM, powder mixed ECDM, magnetic field assisted ECDM, vibration assisted ECDM methods. Pyrex, glass, stainless steel, cermet, soda lime glass, quartz, silicon nitride, zirconium oxide, borosilicate glass, diamond crystals, e-glass/epoxy composite, kevlar/epoxy composite and silicon wafer were used as a work piece. Effects of machining voltage and drilling depth on mean diameter, influence of tool travel rate on groove width and depth and effects of voltage types on micro holes accuracy and machining type etc were investigated. This review is to discuss the results of studies and applicability of this methods. It sums up also with a vision for future research in electrochemical micromachining.

“…This may have a positive effect on the mass transfer process, for example, using a reciprocating agitator [10,[29][30][31][32]. Among other methods that are commonly used to intensify solid dissolution, a liquid pulsation [33], electrical discharges [34], other physical methods of the interaction [35], and dissolution on the solid or fluidized bed [36] can be found. In the case of dissolution process with chemical reaction an ultrasound can be used to the intensification [37][38][39].…”

The mass transfer process is the subject of many experimental studies in chemical engineering and also one of the most commonly used processes. Unfortunately, the mechanism of this process is still not fully understood, especially when nonstandard methods of intensification of mass transfer are used. In this investigation, the use of an alternating magnetic field action AMFs causing mass transfer was taking into consideration. As a result of the flow of electrically conductive fluid near the alternating magnetic field, electromagnetic forces can be generated within the liquid.These forces arise as a result of interaction between the magnetic field and the electric current. They are responsible for the rotation and consequently cause movement of the fluid on which they act. Therefore, there is the possibility of using these properties in the construction of a nonintrusive mixing stirrer.The aim of this study is to determine the mixing time, the power consumption and the mixing efficiency in the mass transfer process that is induced under the action of RMF. The present study compared the mass transfer coefficient of two reactor types RMF mixer and stirred tank reactor.
