<br/><br/> Analytical results were made for every variable with respect to the value of the kerf width , microhardness value , HAZ area , oxide layers width and surface roughness valueSEM was made to observe the surface morphology of the cut edgeAnd some photographs were taken for the top and bottom of the cut edgeAlso microstructure analysis was made to some of the specimensAccording to the results of this work , window of the optimum values of the three parameters were obtained , including the best cutting qualityThe results were discussed and compared with previous researchers
