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...

The correct selection of process parameters for manufacturing is one of the most important aspects taken into consideration in the majority of manufacturing processes and particularly, in process related to EDM. The machining characteristics are greatly influenced by the nature of dielectric used during micro-EDM. The present paper investigates the fuzzy logic model for micro-electrical dischar...

Wire electrical discharge machining (WEDM) is a method to cut conductive materials with a thin electrode that follows a programmed path. The electrode is a thin wire. Typical diameters range from .004" - .012" (.10mm - .30mm) although smaller and larger diameters are available. WEDM is a thermal machining process capable of accurately machining parts with varying hardness or complex shapes. WED...

The Electric Discharge (EDM) method is a novel thermoelectric manufacturing technique in which materials are removed by controlled spark erosion process between two electrodes immersed dielectric medium. Because of the difficulties EDM, determining optimum cutting parameters to improve performance extremely tough. As result, optimizing operating critical processing step, particularly for non-tr...

Pulse generator is the key equipment of electrical discharge machining (EDM). Considering the disadvantage of the traditional EDM pulse generator, a new pulse generator based on VB and SCM is designed. The simulation and serial communication with SCM are achieved, and the pulse width, pulse period, and phase sequence difference can be adjusted by the upper computer at a wide range. The simulati...

Whereas the efficiency of traditional cutting processes is limited by the mechanical properties of the processed material and the complexity of the workpiece geometry, electrical discharge machining (EDM) being a thermal erosion process, is subject to no such constraints. The base material used for this study was an AISI 1045 steel with copper electrode. This study highlights the development of...

Present work aims at multi-mechanical surface treatment of Ti-6Al-4V based-miniplate implant manufactured by electrical discharge machining (EDM) for biomedical use. Mechanical surface treatment consists of consequent use of ultrasonic cleaning, rotary tumbler polishing, and brushing. Surface layers are analyzed employing scanning electron microscopy and energy dispersive X-ray spectroscopy. Al...
