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

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

predictive maintenance check list for cnc machine

All machinery requires routine maintenance. Vertical Machining Centers (VMC) and Horizontal Machining Centers (HMC) are no exception. However, in most manufacturing facilities the emphasis is on production, not machine maintenance. This is to be expected, as the challenges of maintaining profitable production are always foremost in a manufacturer s mind.



CHECKLISTThat s why it makes perfect sense to consider a VMC or HMC preventative maintenance program from Gosiger. Our technical service ....etc

SYNOPSIS
Wire Electric Discharge Machining(WEDM) is one of the most important non-traditional machining process.Taguchi method is supplemented with various supportive techniques such as fuzzy logic, grey-relational analysis,two-phase parameter design, artificial neural network(ANN) and various combination methods to incorporate material removal rate(MRR) and surface roughness(SR)simultaneously .Particle Swarm Optimization(PSO)& Memetic Algorithm(MA) based optimization procedures have been developed to o ....etc
