The electrochemical discharge machining (ECDM) is a nontraditional integrated method can be useful for cutting all types of materials. In this chapter, the influence of input factors, i.e., concentration of electrolyte, voltage, and rotation speed on average material removal rate (MRR), average hole diameter, as well as average machined depth on drilling on soda-lime glass is analyzed. The gunmetal material tool electrode was used as cathode in electrochemical discharge machining for experimentation, and it is optimized by Taguchi methodology in addition with Grey relational analysis. Based on the current investigation, the optimum input factors were determined. The results illustrate the maximum average material removal rate, raised average hole diameter as well as maximum average machined depth which were found to be 75 V applied voltage, 20% concentration of electrolyte, and 50 rpm rotational speed.
