Abstract:

This present experimental work is to find out the optimize input process parameters of powder mixed electrical discharge machining (PMEDM)on OHNS-O2 with graphite powder. Taguchi design is used to found out the optimized value and to analyze the experiments. Analysis were done to investigate the effects of the process parameters viz. pulse on time (Ton) , pulse off-time (Toff)& current and concentration of the Sic powder in IPOL dielectric (C) and its effects on material removal rate (MRR), surface roughness (Ra),and process parameters were optimized for high MRR, low Ra and machining timing using Taguchi function approach of MINITAB software.optimal factor for Surface Roughness was obtained, and conventional EDM process is undergone for the obtained surface roughness factor.Both process Roughness value are compared and found that the PMEDM process is better than conventional EDM process.
