Machining performance of high energy die-sinking electrical discharge machining on GH2132

, 2020
Superalloys are typical “difficult to machine” materials, which could be processed by electrical discharge machining (EDM). The studies about the machining performance of superalloys mainly concentrate on nickel-based superalloys and titanium superalloys.

Electrical discharge machining in distilled water

Wear, 1981
Abstract The performances of kerosene and distilled water as the dielectric fluid in electrical discharge machining (EDM) were compared over the pulse energy range 0.72 – 288 mJ. Machining in distilled water resulted in a higher metal removal rate and a lower wear ratio than in kerosene when a high pulse energy range (72 – 288 mJ) was used.

Mechanism of Electrical Discharge Machining Ablation

Materials and Manufacturing Processes, 2014
A single-pulse experiment was conducted to study the mechanism of electrical discharge machining (EDM) ablation. An equivalent model of EDM ablation was established to explain the changes in the oxide layer of electrodes. Theoretical analysis was performed to understand the machining mechanism behind EDM ablation.

Discussion of electrical discharge machining in gas

The 31st IEEE International Conference on Plasma Science, 2004. ICOPS 2004. IEEE Conference Record - Abstracts., 2004
Summary form only given. For the microcosmical understanding of electrical discharge machining (EDM) in gas (dry EDM), the influences of such parameters as polarity and gas pressure on EDM in gas were discussed based on theory of gas discharge and experiments; meanwhile, the influencing factors of material remove rate (MRR) in dry EDM and reasons for ...

Microcomputer-Controlled Electric Discharge Machine

IETE Journal of Research, 1978
Principle of operation of EDM is briefly outlined. It is shown that the automatic nature of this unconventional machine lends itself easily to computer control. The parameters to be computer-controlled for maximum machining efficiency are discussed with particular reference to the interface required.
