Establish control over process parameters on ECM for improving the MRR of 12X18H10T - Stainless steel

Electrochemical machining is a class of NTM (Non-Traditional Machining) widely applicable for machining the precious components like tools and dies. The importance of this research is one of the main drawback in NTM is slow process that is Low MRR. This research is about Machinability Investigation and optimizing Process parameters on electrochemical machining (ECM) for improving rate of machining of Stainless Steel (12X18H10T). In this investigation the core process parameters like electrode gap, current, voltage and concentration of electrodes were considered as process variables for optimizing the rate of machining or material removal rate (MRR). The input variables were varied three levels as minimum, medium and maximum settings. The range of individual process parameters were identified by trail experimentations. The Taguchi L9 experimental design adapted for 3 level 4 factor design to conduct the experimentation and statistical optimization by Taguchi analysis. The optimized parameters were validated by trail experimentation and found acceptable error. The ANOVA used for validate the statistical model identifying theinfluence of process parameters. The optimized values of process parameters suggested and the mathematical model developed to predict the process parameters settings for the required MRR.
