TL;DR: The workpiece machined by EDM depends on thermal conductivity, electrical resistivity, and melting points of the materials as discussed by the authors, and the tool and the workpiece are adequately both immersed in a dielectric medium, such as, kerosene, deionised water or any other suitable fluid.
Abstract: Electro discharge machining (EDM) process is a non-conventional and non-contact machining operation which is used in industry for high precision products. EDM is known for machining hard and brittle conductive materials since it can melt any electrically conductive material regardless of its hardness. The workpiece machined by EDM depends on thermal conductivity, electrical resistivity, and melting points of the materials. The tool and the workpiece are adequately both immersed in a dielectric medium, such as, kerosene, deionised water or any other suitable fluid. This paper provides an important review on different types of EDM operations. A brief discussion is also done on the machining responses and mathematical modelling.

TL;DR: A machining method, especially an electro-erosion wire cutting machining, in which a machining gap (4) is formed between core (2) and workpiece (1), a core is cut out of the workpiece and the core is secured against falling out, is characterised in this article.
Abstract: A machining method, especially an electro-erosion wire cutting machining method, in which a machining gap (4) is formed between core (2) and workpiece (1), a core (2) is cut out of the workpiece (1) and the core (2) is secured against falling out, is characterised in that the core (2) is secured by at least one separate means (3) arranged in the machining gap (4). The means (3) is preferably cut out of the workpiece (1) by electro-erosion. … …

TL;DR: In this article, it has been shown that although the amount of material removed from the anode and the cathode varies appreciably with several operating parameters, the total weight of metal removed from both is practically constant.
Abstract: The erosion of electrodes during an electric discharge in a liquid dielectric medium has been studied by measuring weight loss. It has been shown that, although the amount of material removed from the anode and the cathode varies appreciably with several operating parameters, the total weight of metal removed from both is practically constant. A physical interpretation of this property is proposed which may lead to a better understanding of the processes of material removal and thereby improve the operating conditions of electroeroding machines in particular by transferring the erosion process from the tool to the work piece.

TL;DR: A rotary shaver as discussed by the authors is equipped with an outer blade in which multiple beard-accepting holes are formed in the shaving surfaces that form ring-shaped protrusions and an inner blade that rotates in contact with ringshaped shaving grooves of the lower surface of the outer blade.
Abstract: A rotary shaver, which is equipped with an outer blade in which multiple beard-accepting holes are formed in the shaving surfaces that form ring-shaped protrusions and an inner blade that rotates in contact with ring-shaped shaving grooves of the lower surface of the outer blade, and which cuts hair that enters the beard-accepting holes of the outer blade using the inner blade. The outer blade is formed into the disc-shaped outer blade shape by machining beard-accepting holes in a metal sheet and drawing the metal sheet. Deep drawing of the metal sheet is not always required, the use of special drawing molds, cutting, or difficult machining methods such as ECM or electric discharge machining is not necessary, and productivity can be significantly improved. The machined shape of the beard-accepting holes is not limited to straight lines, making it possible to increase the degree of freedom in designing the shaving surface. The rotary shaver is also suitable for reducing the weight thereof.

TL;DR: Feed—forward reverse dissemination neural network base on top of very important composite rotatable investigational drawing mechanism, developed to model machining procedure, and employ Artificial Neural Network.
Abstract: Micro electrical Discharge Machining Drilling (MEDM Drill) technology has recently come into existence. The MEDM Drill process is an amalgamation of electromagnetic, thermodynamic and hydrodynamic behaviour and stochastic in nature. Optimize the course of action parametric combination, modelling the method, employ Artificial Neural Network (ANN) as well as to characterize the MEDM Drill external from end to end time progression technique. Therefore feed—forward reverse dissemination neural network base on top of very important composite rotatable investigational drawing mechanism, developed to model machining procedure. The best possible parametric combination is particular for development.
