State of the art electrical discharge machining (EDM)

International Journal of Machine Tools and Manufacture, 2003
Abstract Electrical discharge machining (EDM) is a well-established machining option for manufacturing geometrically complex or hard material parts that are extremely difficult-to-machine by conventional machining processes. The non-contact machining technique has been continuously evolving from a mere tool and die making process to a micro-scale ...

Spark Gap System of Electrical Discharge Machining (EDM)

2019 6th International Conference on Information Technology, Computer and Electrical Engineering (ICITACEE), 2019
EDM is a process of machining electrically conductive materials by precisely controlled electrical discharge through a small clearance gap that occur between an electrode and a workpiece in the presence of a dielectric fluid. Through EDM process, the material of workpiece are melted and gap distance will increase.

Power Generator of Electrical Discharge Machining (EDM) System

Applied Mechanics and Materials, 2014
Electrical Discharge Machining (EDM) is a non-conventional manufacturing process of removing materials. The uniqueness of EDM process is the removal of the unwanted materials without direct contact between the electrode and workpiece. EDM power generator provides power source of EDM system.

Electrical Discharge Machining (EDM) Characteristics Associated with Electrical Discharge Energy on Machining of Cemented Tungsten Carbide

Materials and Manufacturing Processes, 2008
In this investigation, cemented tungsten carbides graded K10 and P10 were machined by electrical discharge machining (EDM) using an electrolytic copper electrode. The machining parameters of EDM were varied to explore the effects of electrical discharge energy on the machining characteristics, such as material removal rate (MRR), electrode wear rate ...

Microanalysis of debris formed during electrical discharge machining (EDM)

Journal of Materials Science, 2007
The present investigation attempts to focus on the influence of EDM energy input on the structure and composition of the debris that forms during machining. An indigenously prepared ZrB2-Cu composite and mild steel plate were used as tool and workpiece (WP) material for the present study. The machining was carried out in a kerosene medium.

Analysis and control of electrical discharge machining (EDM) process

2009 IEEE International Conference on Industrial Engineering and Engineering Management, 2009
A time series of gap states reflecting electrical discharge machining (EDM) process is used to analyze the process. In linear analysis autocorrelation function and power spectral densities are computed to grade machining powers in different sub processes; in nonlinear analysis surrogate data method is used to prove the deterministic nonlinearity of a ...

Electrical Discharge Machining (EDM): Selection of Dielectric in Machining ASSAB 718HH

Advanced Materials Research, 2012
Electrical Discharge Machining (EDM) in Malaysia is widely used in mould making industries. Parts for automotive, defence and telecommunication industries are also other examples of the products produced. The process is based on removing material from a part by a series of repeated electrical discharges between a tool called electrode and the work ...

Developments in electric power supply configurations for electrical-discharge-machining (EDM)

The Fifth International Conference on Power Electronics and Drive Systems, 2003. PEDS 2003., 2004
The electric discharge machining (EDM) process provides one of the best alternatives, or sometimes the only alternative, to machine a growing number of high-strength and corrosion-and-wear-resistant materials. It is based on the principle of erosion of metals by an interrupted electric spark.
