The differences between the Electrochemical Mechanical Machining (ECMM) progress of Particle Reinforced Metal Matrix Composites (PRMMC) and normal metal are the behaviors of non-conductive Particles. This paper employed Finite Element Method (FEM) to analyze the electrochemical reaction around the particle under different parameters. To seek applicable process, the electric filed analysis in the interelectrode gap of the ECMM process with the embedded tools has been adopted. Experiments about work voltage, electrode gap and the formula and concentration of electrolyte dissolution have been done. Through an ECMM hybrid process combined with a fast back grinding process, a surface about Ra 0.5um of PRMMC has been achieved.
