ABSTRACT
This chapter explains the role of each machining parameter in determining the quality of the machined surface and machining time. The energy transferred to the electrode and the efficiency of debris flushing method are the two key elements that influence the material removal efficiency. Discharge energy is controlled by controlling the voltage, capacitance, peak current, pulse duration, and pulse interval. Debris evacuation from the machining zone is affected by tool rotation speed, the radius of orbital motion, dielectric flow pressure, and eroded material volume. Understanding the variation in machining performance parameters such as MRR, surface roughness, taperness, overcut, and so on with respect to change in electrical and nonelectrical parameters will help to determine the optimum working conditions for stable machining.
