Research development of Powder mixed electro discharge machining (PMEDM)

Abstract

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 power 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.
