This paper deals with Electrochemical machining method to find the material removal rate, surface roughness and overcut by electrochemical dissolution of an anodically polarized work piece (AISI304 s tainless steel) with a copper electrode of hexagonal cross section. Experiments were conducted to analyze the influence of machining parameters such as feed rate, voltage and electrolyte concentration. Analysis of variance (ANOVA) is employed to indicate the level of significance of machining parameters. It is observed that concentration is the most significant factor for response of material removal rate and in case of surface roughness voltage is the most significant factor. For response of overcut, the voltage is most significant factor. The factors also affect the performance are discussed and elaborated. Key Words: Electrochemical Machining (ECM), Material removal rate, Surface roughness, Overcut, Analysis of variance (ANOVA)
