Effect on Material Removal Rate and Surface Finish in ECM Process When Machining Stainless Steel-316 with Cu Electrode

Electrochemical Machining process is one of the popular non-traditional machining processes which is used to machine materials such as super alloys, Ti-alloys, stainless steel etc. Its working principle is based upon Faraday law of electrolysis. The aim of the present work is to optimize the ECM process parameters with the combination of SS 316 (job material) and Copper electrode (tool material). To explore the effect of ECM process parameters such as electrolyte concentration, voltage and current, feed rate on MRR and surface finish (Ra) of the job, total 27 experiments were conducted as per experimental scheme. The results of these experiments revealed that increase in electrolyte concentration decrease the mrr and surface roughness initially increases then decreases. Further, increase in current increases mrr initially and then decreases, surface roughness also increases. It is also noticed that increase in Feed rate mrr decreases and then increases, also surface roughness decreases then increases. Through RSM analysis it is found that the optimum conditions for maximum MRR, and minimum Surface roughness (Ra) is electrolyte concentration 150gm/lit, Voltage 13.5 V & feed 0.8 mm/min. The findings are discussed in the light of previous researches and subsequently conclusions are drawn.

Application of selective membranes in grape juice stabilization

An electrodialytic membrane separation procedure for the grape juice stabilization from potassium tartrate precipitation has been considered and investigated. The best promising processing, as a new technological trend has been achieved by cationic membrane pairs, most particularly with DuPont's Teflon based Nafion 39O ones: potassium ions were removed below their critical content defined by the solubility product with tartrale ions, while the acidity remains within tolerable limits and being positively evaluated. It has been shown that the separation process follows Faraday law of electrolysis down to the final exhaustions of potassium ions thereby providing directly the contact time of the stabilization. At the same time it represents a new economical mean to drastically reduce potassium ion content in smaller amount of juice and further to adjust the final composition by mixing it with larger quantities of raw material. Cationic - anoinic membrane pairs for both potassium and tartrate ionic separation has also been tried and considered. The effect of electrodialytic separation on grape juice composition and stability has been investigated and given.
