CUTTING PARAMETERS OPTIMIZATION FOR THE WIRE EDM PROCESS USING CONTINUOUS ANTS COLONY ALGORITHM (CACO)
ABSTRACT:
Optimization of operating parameters is an important step in machining, particularly for operating unconventional machining procedure like Wire EDM .The economy of machining mainly depends on the machining parameters. Optimization of machining parameters is an important step and has been dealt by many researchers. In this paper ....etc

Chemical Mechanical Planarization (CMP) is an important process in semiconductor chip fabrication. In the CMP process, excess material is removed and the surface is planarized by the action of chemical and mechanical forces. Shallow Trench Isolation (STI) has become a key technology for device isolation in recent times. In this method, a shallow trench is made on the silicon wafer between active devices, silicon dioxide is deposited over the trench as well as the active area and the excess silicon dioxide is removed by CMP. The oxide remaining ....etc

Finite-Element Simulation of Electrical Discharge Machining (EDM) Process


I. INTRODUCTION
Electric discharge machining (EDM), sometimes
colloquially also referred to as spark machining, spark
eroding, burning, die sinking or wire erosion, is a
manufacturing process whereby a desired shape is obtained
using electrical discharges (sparks). Material is removed
from the workpiece by a series of rapidly recurring current
discharges between two electrodes, se ....etc
