Research development of Powder mixed electro discharge machining (PMEDM)

fajar nur ali


This paper describes improvement of fuzzy logic model for powder combined electro discharge machining (PMEDM) method. The developed fuzzy version implements triangular and trapezoidal membership functions for fuzzification and centre-of-location technique for defuzzification processes. The technique parameters decided on as manipulate variables for experimental work were tool fabric, type of powder, concentration of powder in dielectric medium and height cutting-edge. The machining operation becomes carried out via using copper and graphite as electrode material on mild steel workpiece cloth. The powder additives used inside the experiment have been aluminum and silicon due to their notably exceptional electrical and thermal homes. The dielectric fluid used turned into kerosene. The response parameters selected are material removal fee and electrode wear price. Reaction surfaces are developed from the developed fuzzy device version. Additionally exemplar plot developed to examine the responses from fuzzy version and experiment.
