Off-line programming and simulation for 2-axis wire EDM

Computer simulation of wire-EDM taper-cutting

Wire electro discharge machining (WEDM) has become one of the most popular processes for producing precise geometries in hard materials, such as those used in the tooling industry. Since it is recognized as a precision process, optimization of different aspects related to dimensional accuracy is a classic research topic. The so-called tapercutting involves the generation of inclined ruled surfa...

Robot simulation and off-line programming - Computer-Aided Engineering Journal

Robot simulation and off-line programming seem likely to have an increasingly important role in the evolution of C IM facilities. This article considers the capabilities and shortcomings of the current generation of off-line programming and graphical simulation systems. Methods of overcoming problems associated with calibration, lack of ‘user friendliness’ and integration within manufacturing s...

Modeling and Optimization of Wire EDM Process

The present work is aimed to optimize the parameters of (WEDM) process by considering the effect of input parameters viz. Time On, Time Off, Wire Speed & Wire Feed. Experiments have been conducted with these parameters in three different levels data related to process responses viz. Metal removal rate, surface roughness (Ra) have been measured for each of the experimental run. These data have b...

Stochastic programming for off-line adaptive radiotherapy

In intensity-modulated radiotherapy (IMRT), a treatment is designed to deliver high radiation doses to tumors, while avoiding the healthy tissue. Optimizationbased treatment planning often produces sharp dose gradients between tumors and healthy tissue. Random shifts during treatment can cause significant differences between the dose in the “optimized” plan and the actual dose delivered to a pa...
