“…As the tool advances towards work, gap decreases and current increases which increases more metal at a rate corresponding to tool advance [19]. A stable spacing between tool and work is thus established.…”

“…Despite many mathematical models predicting the tool geometry required for a given machine profile, in practise often an empirical approach is used in tool design. As a consequence, the overall cost of the ECM process can be relatively high 46 ). An ECM process using universal tool-electrodes, such as, flat or cylindrical shape has been proposed as a solution to the problems in ECM tool design 53 ),54).…”

This paper reviews the most recent trends in research and development in electrochemical machining (ECM). ECM has been applied in industries such as aerospace, automobile and defence. The process advantages of ECM rendering the technology more applicable in other industries, especially where complicated shapes of parts and high reliability are expected. In this paper advances in ECM are presented and discussed in fields such as: micro-ECM, pulsed-ECM, ECM tool design and hybrid ECM processes. The environmental implications for ECM are explored. Machining of highly passivating and non-conductive materials is discussed. Innovative ECM applications are described.

“…[7,8] developed a numerical simulation of ECM using a 2D model based on a moving boundary problem which was solved by using a finite element difference (FED) method. In parallel, Kozak [9][10][11] built a physical and mathematical model of the ECM process in order to find the optimal machining conditions and tool design that would lead to an expected workpiece profile. [12] reported the development of an empirical model based on the characteristic relationships within the ECM process parameters in order to increase its precision.…”

“…When considering the inclusion of the diverse phenomena occurring during ECM, [9,18] developed 2D mathematical simulation models that took into account ohmic heating and gas fraction influence on the electrolyte conductivity. Later, [19,20] described in their studies the effects that the heat generated by electrode reactions has on the accuracy of the process.…”

In electrochemical machining (ECM)-a method that uses anodic dissolution to remove metal-it is extremely difficult to predict material removal and resulting surface finish due to the complex interaction between the numerous parameters available in the machining conditions. In this paper, it is argued that a 3D coupled multiphysics finite element model is a suitable way to further develop the ability to model the ECM process. This builds on the work of previous researchers and further claims that the overpotential available at the surface of the workpiece is a crucial factor in ensuring satisfactory results. As a validation example, a real-world problem for polishing via ECM of SS316 pipes is modelled and compared to empirical tests. Various physical and chemical effects, including those due to electrodynamics, fluid dynamic, and thermal and electrochemical phenomena, were incorporated in the 3D geometric model of the proposed tool, workpiece, and electrolyte. Predictions were made for current density, conductivity, fluid velocity, temperature, and crucially, with estimates of the deviations in overpotential. Results revealed a good agreement between simulation and experiment and these were sufficient not only to solve the immediate real problem presented but also to ensure that future additions to the technique could in the longer term lead to a better means of understanding a most useful manufacturing process.
