Experimental Investigation on ECMM With Nimonic 75 Alloy for Prosthetic Component
Electrochemical micromachining is an advanced technology of recent trends of machining of hard and electrically conductive materials in micrometer and sub-micrometer scale. This manufacturing technique finds application in many technologically demanding industries: locomotive, biomedical, electronics, etc. However, due to very small inter-electrode gap, there is some limitation in using this machining process. This chapter aims at developing an optimized model for flow analysis of electrolyte in inter-electrode gap to obtain optimal process parameter for machining. Experimentation has been done to associate the findings of optimized output in ECMM such as material removal rate (MRR), overcut, and depth. Influence of voltage, feed rate, concentration, pulse on/pulse off ratio, and IEG investigated and finally optimized using response surface method. The effect of the process parameters are also analyzed using ANOVA.
