A mathematical model to choose effective cutting parameters in electroerosion, EDM



introduction

Machining by electroerosion experienced a significant development during the last decades when several problems were caused following the metallographic and mechanical change of the machined surface. Several research tasks are interested in the study of optimization and the improvement of the various performances of machining by electroerosion in order to improve the productivity and the precision of ....etc

weight operated material handling vechile

Material handling equipment is mechanical equipment used for the movement, storage, control and protection of materials, goods and products throughout the process of manufacturing, distribution, consumption and disposal. The different types of material handling equipment can be classified into four major categories:transport equipment, positioning equipment, unit load formation equipment, and storage equipment. ....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, separated by a dielectri ....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

Lottery Tips and Tricks
The lottery is a game of chance rather than a game of skills. You can just use any lottery strategy to predict winning numbers. However, here you can find tips provided by some lottery experts. As usual, suggestions are considered a controversial topic and you should study them with the critical mind. But anyway, it's best to know as much as possible when you decide to embark on anything. Who knows, maybe one day these tips will help you pick up more winning numbers from the lottery or at least eliminate numbers ....etc
