“…In view of difficulties encountered e.g. high tool wear and high tooling cost, during conventional machining, non-contact material removal processes such as the electric discharge machining (EDM) offer an effective alternative [5]. Lloyd (1994) reported that vortex mixing technique was suitable for the preparation of ceramic particle dispersed aluminum composite [6].…”

“…The experiments were carried out for a depth of cut of 2 mm for all electrode materials with five different pulse current settings of 6 A, 12 A, 18 A, 24 A and 30 A. Material removal rate (MRR) is expressed as the ratio of difference of weight of the work piece before and after machining to the machining time [13].…”

Electric Discharge Machining (EDM) is one of the most efficiently employed non-traditional machining processes for cutting hard-to-cut materials, to geometrically complex shapes that are difficult to machine by conventional machines. In the present work, an experimental investigation has been carried out to study the effect of pulsed current on material removal rate, electrode wear, surface roughness and diameteral overcut in corrosion resistant stainless steels viz., 316 L and 17-4 PH. The materials used for the work were machined with different electrode materials such as copper, copper-tungsten and graphite. It is observed that the output parameters such as material removal rate, electrode wear and surface roughness of EDM increase with increase in pulsed current. The results reveal that high material removal rate have been achieved with copper electrode whereas copper-tungsten yielded lower electrode wear, smooth surface finish and good dimensional accuracy.

“…The increase in the peak current increases the MRR, TWR and ROC significantly in a nonlinear fashion, MRR and ROC increased with the increase in the pulse on time and the gap voltage was found to have some effect on the three responses. 5,6 The influence of electrochemical process parameters such as the applied voltage, electrolyte concentration, electrolyte flow rate and tool feed rate on the metal removal rate and surface roughness to fulfil the effective utilization of electrochemical machining can be used. 7 For non-passivating electrode systems, the reduction in electrolyte concentration and an increase in its temperature improve the quality of surfaces.…”

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
