“…The prediction of shape evolution during high rate anodic dissolution requires solving the current distribution at the anode along with a moving boundary algorithm. The current distribution at the anode depends on geometry, anode reaction kinetics, electrolyte conductivity and hydrodynamic conditions [4]. Current distribution is calculated for a given time using appropriate finite difference, finite and boundary element codes.…”

“…However, except for electrochemical jet machining, electrochemical etching and wire electrochemical grinding, ECM still lags far behind other processes such as electric discharge machining (EDM) in the precision and micro-machining fields [7][8][9][10]. For the purpose of precise micro-machining, it is necessary to predict the final shape formed by the process when the machining parameters are given.…”

Electrochemical machining (ECM) has been increasingly recognized as a potential tool for mini-scale machining. Using the ECM process to erode a hole of hundreds of micrometres on a thin metal sheet is analysed in this paper. The purpose of this study is to predict the hole formation, particularly when boring through the hole. A theoretical method is presented to illustrate how the machined profile evolves. The analysis is based on the fundamental law of electrolysis and the integral of the electrochemical reaction over the finite width of the tool electrode. A concept of redistribution of electric charge is adopted in the model when the hole is bored through. The approach of the model is verified experimentally.

“…11 The electrolyte temperature, pressure variations in the inter electrode gap and the choice of an optimum gap voltage also avoid the occurrence of sparking and the consequent loss of the tool and workpiece. 12 A metal-matrix composite (MMC) contains matrix materials where reinforcements can be made from polymers, ceramics or metals. MMCs are divided into composites reinforced by fibres (fibrous composites) and composites filled with fine particles that are insoluble in the base-metal-strengthened composites.…”

In this study the mechanical and microstructural behaviours of AA6061 reinforced with silicon carbide (SiC) and AA6061 reinforced with boron carbide (B4C), obtained from the enhanced stir-casting process, were investigated using scanning electron microscopy (SEM) and X-ray diffraction (XRD) with various weight percentages, i.e., 2.5 %, 5 % and 7.5 %. The testing shows that the tensile and microhardness properties of the AA6061 were improved in both the reinforced aluminium-matrix composites. The influence of the electrochemical machining process parameters like current, voltage, electrolyte concentration, feed rate, gap and flow rate were considered as the input parameters. The output responses are the material removal rate (MRR), the surface roughness (SR) and the radial overcut (ROC). The study shows that the dominant output parameter MRR was directly proportional to the input parameters current, voltage and feed rate. The SR was significantly influenced by the input parameters current, feed rate and gap. The ROC was considerably balanced by the input parameters current and feed rate. Keywords: metal-matrix composites, material removal rate, electrochemical machining, surface roughness, radial overcut V {tudiji so bile preiskovane mehanske lastnosti in mikrostruktura AA6061, izdelanega z naprednim postopkom ulivanja s preme{avanjem in oja~anega z razli~nim masnim dele`em silicijevega karbida (SiC) ali borovega karbida (B4C) (2,5 %, 5 % in 7,5 %). Preiskave so bile izvedene s pomo~jo vrsti~nega elektronskega mikroskopa (SEM) in z rentgensko difrakcijo (XRD). Preizku{anje ka`e, da sta natezna trdnost in mikrotrdota AA6061 narasli pri obeh vrstah kompozita na osnovi aluminija. Za vpliv vhodnih procesnih parametrov pri elektrokemijski strojni obdelavi so bili upo{tevani: tok, napetost, koncentracija elektrolita, hitrost podajanja, re`a in hitrost pretoka. Izhodni odgovori so bili: hitrost odstranjevanja materiala (MRR), hrapavost povr{ine (SR) in pove~anje radiusa (ROC). [tudija ka`e, da je prevladujo~i izhodni parameter MRR neposredno proporcionalen vhodnim parametrom; toku, napetosti in hitrosti podajanja. Na SR so mo~no vplivali vhodni parametri: tok, hitrost podajanja in re`a. ROC je bil posebej uravnote`en z vhodnima parametroma, tokom in hitrostjo podajanja. Klju~ne besede: kompoziti na kovinski osnovi, hitrost odstranjevanja materiala, elektrokemijska strojna obdelava, hrapavost povr{ine, pove~anje radiusa
