Electrical breakdown induced by systematic electrostatic discharge (ESD) stress of thin-film transistors used as switches in active matrix addresses liquid crystal displays has been studied using electrical measurements, electrical simulations, electrothermal simulations, and postbreakdown observations. Breakdown due to very short pulses (up to 1 s) shows a clear dependence on the channel lengt...

Electrical discharge machining (EDM) is highly utilized in manufacturing sectors owing to its ability to machine high strength materials with complex shape. The pulse duration of the pulse generator highly determines the machinability in such process. Since the duty factor can characterize the pulse duration, it is very essential to analyze its effect on machinability in the process. In the pre...

The correct selection of manufacturing conditions is one of the most important aspects to take into consideration in the majority of manufacturing processes and, particularly, in processes related to Electrical Discharge Machining (EDM). It is a capable of machining geometrically complex or hard material components, that are precise and difficult-to-machine such as heat treated tool steels, com...

in the present paper, the study has been made to optimize the process parameters during machining of Inconnel-600 by wire electrical discharge machining (WEDM) using response surface methodology (RSM). Four input process parameters of WEDM (namely Peak Current (IP), Pulse-On time (TON), Pulse-Off time (TOFF) and Wire Feed rate (WF)) were chosen as variables to study the process performance in t...

The safety and environmental aspects of a manufacturing process are important due to increased environmental regulations and life quality. In this paper, the concentration of aerosols in the breathing zone of the operator of Electrical Discharge Machining (EDM), a commonly used non traditional manufacturing process is presented. The pattern of aerosol emissions from this process with varying pr...

Deburring is the finishing technique that is very essential for the manufacturing of precise components. Although there are various methods to remove burrs but sometimes technology requires new innovative ideas for better outcome irrespective of cost. Deburring with greater efficiency and full automation is a difficult task and this thing leads to use unconventional approaches. This research pa...

Electrical Discharge Machine (EDM) is especially used for the manufacturing of 3-D complex geometry and hard material parts that are extremely difficult-to-machine by conventional machining processes. In this paper authors review the research work carried out in the development of die-sinking EDM within the past decades for the improvement of machining characteristics such as Material Removal R...
