This paper develops a computational method for numerical control (NC) of traveling wire electric discharge machining (EDM) operation from geometric representation of a desired cut profile in terms of its contours. Normalized arc length parameterization of the contour curves is used to represent the cut profile and a subdivision algorithm is developed together with kinematic analysis to generate...

The present contribution describes an application of a hybrid approach using fuzzy logic and particle swarm optimization (PSO) for optimizing the process parameters in the electric discharge machining (EDM) of AISI 316LN Stainless Steel. In this study, each experimentation was performed under different machining conditions of pulse current, pulse on-time, and pulse off-time. Machining performan...

There are several methods available for precision cutting of thin metals less than 0.06-inch thick used for these applications, which include materials such as stainless steel, titanium, nickel, and aluminum. The major options, lasers, electric discharge machining (EDM), water-jet, and chemical machining each have a role to play. However, precision fiber laser cutting technology is now emerging...

Micro Electric Discharge Machining is a nontraditional machining process which can be used for drilling micro holes in high strength to weight ratio materials. This present research study deals with the single optimization of micro EDM process using Genetic Algorithm. Mathematical models using Response Surface Methodology (RSM) is used to correlate the response and the parameters. The desired r...

Electrical discharging machining (EDM) has become an outstanding approach in the field of metal cutting especially for conductive metals. It’s very difficult to cut the conducting metals with the aid of traditional machining. The main object of the present work has to investigate the effects of various EDM input parameters like pulse on time (Ton) pulse off time (TOFF) as well as the influence ...

SKD11 has been a widely used tool steel for cold works many years while DC53 is intently developed to replace SKD11. In this paper, the machinability of these two steels was compared in terms material removal rate (MRR), electrode wear ratio (EWR), and arithmetic mean value roughness (Ra) specimen machined by electric-discharge machining. The machining variables involved were time peak current....
