TL;DR: In this article, the authors measured the energy distribution of the tool electrode, the workpiece, and the dielectric fluid in the continuous EDM-sinking process and found that the energy in the tool and the work piece is greater than that in the workpieces independently of the pulse duration.
Abstract: A clear understanding of the energy distribution in the EDM process is very important for the explanation of some phenomena which cannot be explained well up to now. In this paper, methods and results of measuring the energies distributed into the tool electrode, workpiece and dielectric in the continuous EDM-sinking process are described. The energies distributed into the tool electrode and workpiece are obtained by means of measuring the temperatures and removal amounts of the electrode and workpiece, and the energy distributed into dielectric fluid is obtained by measuring the temperature rise of the dielectric fluid after flowing through the discharge gap. It is found from the experimental results that the energy distributed into the tool electrode is greater than that into the workpiece independently of the pulse duration and that the energy distributed the dielectric is quite small compared with the energies into the electrodes and the workpiece.

TL;DR: In this article, a scaling analysis and a full numerical simulation of the governing equations are performed, and the dependence on beam size and temperature increase in the liquid is investigated, with good agreement found among the scaling analysis, numerical simulations and experimental data obtained from a previous study.

28 Aug 1970TL;DR: A reusable electrical connector for making an electrical connection in adverse environments in which the electrical connection is made by passing a contact through a self-sealing, precut opening into a sealed chamber filled with dielectric fluid to electrically contact a contact position in the fluid and which chamber has means for instantaneously adjusting in volume to changes in the ambient pressure or with insertion or removal of the electrical contact to maintain interior portions in equilibrium with the pressure of the environment and to prevent the loss of fluid from the sealed chamber.
