The process parameters of electro -discharge machining for TiC/Ni cermet were optimized. The main process objectives were material removal rate ,side gap and surface roughness. The process parameters include peak current,pulse-on time,pulse-off time,servo voltage,servo speed and cycle of tool retraction. Adopting the signal-to-noise ratio (S/N) and the grey relational analysis methods,the influence of process parameters on material removal rate,side gap and surface roughness has been studied based on orthogonal experiments ,and optimized multi-objective parameters has been chosen. The experimental results show that parameters were better by the optimization of the integrated method of S/N analysis and the grey relational analysis ,also the material removal rate ,side gap and surface roughness were efficiently improved.
