Electrical discharge machining process is one of the most Applicable methods in Non-traditional machining for Machining chip in Conduct electricity Piece that reaching to the Pieces that have good quality and high rate of machining chip is very important. Due to the rapid and widespread use of alloy DIN1.2080 in different industry such as Molding, lathe tools, reamer, broaching, cutting guillot...

Among all non-conventional micro-machining, electrochemical discharge machining (ECDM) is having high quality of material removal rate with zero residual stress. This machining has been accepted as a highly modern technology in micromachining. In this paper an effort has been done on micro drilling of glass using electrochemical discharge machining (ECDM). A fixed tool and a step down transform...

In chemical mechanical planarization, abrasive particles are pushed onto a wafer by a deformable pad. In addition to the pad–particle contact force, surface forces also act between the wafer and the particles. Experimental studies indicate the significance of slurry pH and particle size on the material removal rate MRR . In this work, a model for MRR, including the contact mechanics of multiple...

Electrical discharge machining (EDM) is a wellestablished non-conventional machining process, used for manufacturing geometrically complex or hard and electrically conductive material parts that are extremely difficult to cut by other conventional machining processes. But sometimes poor surface finish and low volumetric material removal rate limits its use in the industry. To diffuse this probl...

original paper   the mass-transfer media plays a significant role on the performance of a packed tower. in this paper three counter-current single-stage packed towers at laboratory scale, randomly packed with two different sizes of two types of packing material were experimentally tested to study the role of the packing on the performance of them in the removal of sulfuric acid mists. gas sampl...

Majority of high volume laser manufacturing processes require high throughput, improved accuracy, and minimal thermal damage to the target material. Diode pumped solid state (DPSS) Qswitched nanosecond pulsed lasers are routinely being used today in the manufacture of semiconductor, microelectronics and solar cells. They offer low noise, high stability, and reliability required for a robust man...

Production rates play important role in the turnover of any industry. In order to increase the production rates, industrial processes are need to be speedup by speeding input parameters such as cutting speeds, feed rates etc. But with the higher speeds and feeds the heat generation also increases between tool-chip, tool and work piece interfaces, which reduce the tool life, product quality and ...

Electrical discharge machining is assessed on the basis of Material Removal Rate (MRR), Tool Wear Rate (TWR), and Surface Roughness (SR). Process parameters that mostly affected the EDM Process are Pulse on Time, Pulse off Time, Discharge Current, Arc Gap and Duty Cycle. This paper reviews research for the optimization and improvement of various performance parameters measured in the experiment...
