Multi-response optimization of WEDM Process Parameters using the AHP and TOPSIS method
The work presents a multi response optimization approach to determine the optimal process parameters in wire electrical discharge machining process. Experiments have been conducted using six process parameters such as discharge current, pulse duration, pulse frequency, wire speed, wire tension and dielectric flow rate each at three levels for obtaining the responses like material removal rate, ...
متن کاملEffects of process parameters on material removal rate in WEDM
Purpose: In this paper, the effects of various process parameters of WEDM like pulse on time (TON), pulse off time (TOFF), gap voltage (SV), peak current (IP), wire feed (WF) and wire tension (WT) have been investigated to reveal their impact on material removal rate of hot die steel (H-11) using one variable at a time approach. The optimal set of process parameters has also been predicted to m...
متن کاملOptimization of process parameters of cryogenic treated D-3 in WEDM by Taguchi Approach
Cryogenic treated high carbon high chromium alloy cold tool steels (D-3) are used in production of high performance dies, punches, blanking and punching tools, extrusion tools, etc. cryogenic treatment is a process of keeping the specimen in cold environment to increase its wear resistance and relieving its residual stresses. Due to its high hardness Wire Electric Discharge Machine (WEDM) seems...

15 صفحه اولOptimization of wire electrical discharge machining (WEDM) process parameters using genetic algorithm
Wire electrical discharge machining (WEDM) is a special form of traditional electrical discharge machining in which the electrode is a continuously moving conducting wire. The mechanism of metal removal in wire electrical discharge machining involves the complex erosion effect from electric sparks generated by a pulsating direct current power supply. The sparks generated between two closely spa...
