Controlling and Optimization of Machining Performance Parameters for WEDM Process by using Fuzzy Logic Control System

BrassandNano-coatedBrasscuttingwireswith0.25mmdiameterusedinwireelectricaldischarge machining (WEDM) process. Feeding speed, duty factor, wire tension, wire speed and water pressure were the machining conditions or parameters of WEDM process that conceded in the presented paper. How to control the values of machining conditions during WEDM process for getting best results for metal removal rate, tool wear rate and workpiece surface roughness which were the main significant responses during (WEDM) process is the main aim of that paper.Fuzzy logic control system (FLCS) used for that purpose, it controls the values of the machining conditions, feeding speed (Fs), duty factor (D), wire tension (T), wire speed (Ws)and waterpressure(P).to get best values for performanceparameters, metal removesrate(MRR),toolwearrate(TW),and workpiece surface roughness(Ra
